Between Two Breaths

The sea, once it casts its spell, holds one in its net of wonder forever.
—Jacques-Yves Cousteau, Life and Death in a Coral Sea

London, England

Rain hammered the glass walls of the Canary Wharf tower block, dissolving the city into a smear of grey and neon. Inside an office cubicle on the thirty-second floor, Naia Mitchells’s monitor glowed aquarium-blue, leeching colour from her skin.

There were multiple tabs open on her dual screens: code bugs, angry emails, Slack messages from her manager. Another delayed launch, another promise that next week would bring some relief, if she and the team pushed just a little harder.

But it had already been eighteen unrelenting months, and Naia was drowning in work, gasping for air in the snatched hours away from her desk.

Tom from down the hall ducked into her cubicle. “Drink, Naia? You look like you could use one.”

Naia looked up as rain lashed the glass with renewed energy. Thunder rolled somewhere beyond the lime‑green safety lights. She imagined the Thames rising, swallowing each level one by one until there was nothing left but silence.

She nodded at her screen. “Deadline. Maybe tomorrow.”

Tom walked away, and the voices of the team grew softer as the office quietened. Naia swallowed a couple of caffeine pills along with more painkillers. It would be enough to keep the headache and back pain at bay, at least for now. Her doctor had prescribed magnesium tablets, mindfulness apps, and a holiday she never managed to take. “You can’t keep swimming forever,” the doctor had said. “At some point, you need to take a breath, or your body will shut you down.”

Another ping from Naia’s email. Another error message in the code. An urgent buzz on her phone.

Panic swelled, pressing against her ribs. Her heart hammered — too fast, too loud. The office walls contracted, the ceiling pushed down. Her breath came in shallow gasps as her vision tunnelled. She gripped the edge of the desk, knuckles white, fighting the sensation that threatened to send her into oblivion.

Only one thing calmed her in this state.

She clicked open another tab, navigating to a travel site. A new article popped up: Top Ten Dive Sites That Will Change Your Life.

She zoomed into the photograph. Turquoise sky overhead, cobalt water below. Arches of volcanic rock framing shafts of sunlight that turned whirling schools of fish into stained glass. Naia’s breathing slowed as she imagined floating alongside them, seeing only water and sky, leaving the stress of city life behind.

When the panic passed, she read the caption beneath the photo. The Poor Knights Islands, Aotearoa, New Zealand, named by the oceanographer Jacques Cousteau as ‘one of the top ten dive sites in the world.’ A place where she could breathe again. A place on the opposite side of the world, where she might escape the glass cage and digital chains that bound her to a life she could barely breathe through.

Naia pushed back her chair, shut down her laptop, and walked out into the rain. The water streamed down her face as she hurried home over the footbridge toward Poplar Dock. This river smelled of iron and industry, and the water was dark and forbidding. If there were any fish down there, she thought they must be mutated and eyeless, blind in the depths, unable to see the light.

She could join them.

A few stones in her pockets and all her stress would be submerged, forgotten.

She hesitated a minute on the edge of the bridge before walking on.

Back home, over a microwave meal, Naia clicked back into the article, then researched how to get to Poor Knights Islands.

A flight from London to Auckland with just a short stopover.

A bus north to Tutukaka, a little port on the Northland coast.

A charter boat out to the islands.

She could swim in that blue sea by the weekend.

Lightning crashed outside as the storm hit in the darkness. Naia’s hand hovered over the booking form. She took a slow, deep breath.

***

Tutukaka, Aotearoa, New Zealand — a week later

The marina smelled of diesel slick and sun‑warmed kelp. The scent of yesterday’s fish and chips still lingered in the air from the kitchens of the Deep Sea Angler’s Club, further along the marina. Gannets wheeled overhead in lazy spirals, and on the weathered pylons, black shags spread their wings to dry. A pied oystercatcher stalked the shallows on bright orange legs, probing for shellfish with its blade-like bill, and below the surface, between the moored charter boats, a short-tailed stingray glided. Its spotted wings undulated through the clear water as it nosed along the sandy bottom, stirring up small clouds of sediment in search of buried crabs and worms.

Naia walked out of the dive shop, carrying a holdall bag containing a rental wetsuit, fins, and mask, with a weight belt over her shoulder. She followed the other tourists down towards the Taniwha waiting at berth twelve, as she tried to calm the nerves and anticipation in her fluttering stomach.

A young man stood at the bow, ushering the day’s students aboard, ticking names on his clipboard. Under his fitted short-sleeved shirt, his arms were the colour of kauri bark, while the blond in his hair was salted almost white. Maori pattern tattoos spiralled from elbow to wrist, koru curls that evoked unfurling fern fronds and ocean eddies.

He waved Naia over. “Welcome aboard, I’m Matt.”

“Hi, I’m Naia Mitchell.”

He ticked her name off. “First time free-diving?”

She nodded. “I can hold my breath for maybe thirty seconds. On land.”

“Don’t worry,” he said with a smile. “It’s not about your lungs. It’s about letting go.”

As Naia joined the others on the boat, his words loosened the tightness in her chest. She was here to let go of late-night coding, fluorescent headaches, the constant stream of notifications and urgent messages.

Let go of her old life.

Let go of who she used to be.

Once everyone was onboard, the Taniwha chugged out of the harbour, beyond the lee of the headland out into the Pacific.

It was a calm day with gentle wind and waves, and in the distance, the silhouette of the islands drew closer with every minute. Two scalloped spines of volcanic rock rose from the water with a rugged tapestry of forest on top. Trees clung to every surface, their gnarled branches twisted by sea winds. Hardy shrubs and clumps of flax filled the spaces between, a testament to life’s tenacity on these sheer cliffs, and as the boat drew nearer, Naia could make out dark mouths of sea-carved caves and arches, gateways to the world below.

The skipper moored the boat in a tranquil bay cradled by the island’s steep cliffs. As he cut the engine, the sudden quiet was broken only by the gentle lap of water against the hull and the cry of a gull circling high above.

The water was a startling shade of turquoise, so clear Naia could see the kelp swaying over rocks fifteen metres below. The fronds swayed in the gentle current, catching shafts of sunlight as a school of blue maomao darted between the boulders.

“Everyone gather round,” Matt called, his voice carrying the calm authority of someone at home on and in the water. “This is Nursery Cove, perfect for beginners. Calm, shallow, protected from the swells. Today’s about getting comfortable, learning to breathe properly, and seeing what’s down there.”

He demonstrated the most effective breathing technique for free-diving, his chest rising and falling in slow, deliberate waves. “Forget everything you think you know about holding your breath. This isn’t about forcing air into your lungs. It’s about relaxing into the water. Never push it. Never dive alone. Trust your body and have fun. Today is all about letting go.”

Naia pulled the wetsuit up over her shoulders, the neoprene snug against her skin. The weight belt, necessary to get her past the initial few meters of buoyancy, settled around her hips with surprising heaviness.

As she adjusted her mask, she became aware of her breathing. It was no longer the shallow, panicked gasps of her London cubicle, but something deeper, slower. The salt air filled her lungs completely, each breath a conscious choice rather than a desperate necessity.

Matt came over and helped her adjust the weight belt. “Remember, the ocean wants to hold you. You just have to let it.”

One by one, the group slipped over the side of the boat.

As Naia entered the water, the shock of the cold made her gasp, a jolt that cleared the last vestiges of jet-lag. It seeped through the neoprene, a creeping chill that was quickly replaced by a layer of warmth as her body heated the trapped water.

Following Matt’s instructions, Naia rolled onto her front, face down in the water, and began her breathe-up, a specific way of relaxing the body and mind — deep, slow breaths in preparation for the dive.

The world above vanished, the sound muted to a distant hum. She focused only on the rhythms of her body.

With each long, controlled exhale, she felt the tightness in her shoulders dissolve. Her heart rate, which had been fluttering with nervous energy, slowed to a steady, deep beat.

She wasn’t fighting for air. She was releasing it, letting it go, just as Matt said.

Just then, he sank past her, his lithe form perfectly streamlined, arms swept back against his sides, the koru spirals seeming to flow with the current. His long fins cut through the water with barely a whisper, propelling him down with an economy of movement. No struggle, no hurried descent, just a fluid, weightless fall toward the rocks below.

At the bottom, he glided between the kelp fronds with the grace of a seal, turning to wave up at the group with languid ease before beginning his ascent. No rush, no panic, just a gentle return to the surface world.

Naia floated, transfixed, as a deep longing unfurled in her chest — for Matt’s skill, and also for the profound peace he clearly felt down there. She wanted to dive deeper into the water, deeper into herself, to find whatever it was Matt had discovered down in the blue depths.

There was only one way to get there.

Naia filled her lungs, folded at the waist, and tried to gracefully descend, but instead found herself flailing, her legs kicking frantically as she fought against her own buoyancy.

The weight belt wasn’t enough to overcome her air-filled wetsuit and nervous energy, and she only managed a few meters before her body betrayed her, lungs burning with the desperate need for air.

She tried again and again, managing to get a little deeper, her ears popping as the pressure built. But her movements were heavy and clumsy, a world away from Matt’s fluid grace.

Her heart hammered against her ribs, eating up precious oxygen. At maybe four meters down, panic crept in, a tightness in her chest, an urge to gasp.

But then, for just a moment, something shifted.

Her body stopped fighting.

The kelp swayed below her, and Naia experienced a fleeting sensation of perfect weightlessness, of belonging. For three heartbeats, maybe four, she glimpsed what Matt found down here.

Then her lungs screamed for air and she kicked hard for the surface, breaking through with a desperate gasp, treading water as she gulped down oxygen.

“Naia!” Matt swam over, concern creasing his features. “You okay?”

She turned to him, and despite the burning in her chest, despite her clumsy technique, she couldn’t stop grinning. A wide smile that matched the one spreading across his own face.

“That was incredible,” she panted, still catching her breath. “Can I go again?”

Matt chuckled. “We’ve got all day. Pace yourself.”

As he swam over to help other students, Naia knew pacing herself would be impossible. The ocean had tilted her internal compass, and every arrow now pointed down.

As she repeated the breathing practice, ready to dive again, she gazed down into the blue. The shadows beckoned, and she tipped forward, chasing the call.

***

Four months later

Salt spray silvered the warped wooden boards beneath her bare feet as Naia unfurled her yoga mat on the hostel deck. Dawn light bleached the horizon pale gold, and the far off Poor Knights Islands rose from the Pacific, their volcanic silhouettes softened by morning mist.

Naia settled cross-legged, closing her eyes as she inhaled the cool morning air. Inhale for four… hold for seven… exhale for eight.

The breathing pattern flowed through her easily now, each cycle drawing her deeper into stillness. Her ribs expanded slowly, deliberately, no longer the shallow gasps that once kept her afloat in that glass tower back in Canary Wharf.

Here, breathing was meditation.

Breathing was ritual.

Breathing was preparation for the deep blue that called to her from beyond the reef.

Naia flowed through sun salutations as the light strengthened, her movements liquid and unhurried. The cramped hostel accommodation with its thin mattresses, shared bathroom, and walls that shook when the wind picked up would have horrified the woman she used to be. She had once measured worth in thread counts and postcode prestige, in the gleaming penthouse windows that reflected nothing but emptiness. Money for selling her soul, pixel by pixel. Luxury that was only ever a gilded cage.

And now this. A creaking deck, a second-hand yoga mat, a view of the islands that Cousteau himself had blessed. This was wealth beyond measure.

Here she traded her work in the dive shop for hours out on the boat, her physical labour for time beneath the surface. No shareholders, no deadlines, no fluorescent headaches.

Just the rhythm of tides and the promise of depth.

Naia slid into warrior one pose, feeling the strength of her muscles as she extended her arms out. Her hair had grown long and sun-bleached, no longer the sharp bob that framed her pinched, pale face back in London. Her skin, once translucent from office lighting, now held the gold of the Pacific sun and the kiss of salt spray. The old Naia existed only in photos on her abandoned social media accounts, a digital ghost trapped in a glass tower. This woman, stretching into the dawn with lungs that knew their true capacity, had shed that skin and emerged reborn from the depths.

By eight o’clock, Naia was crewing on the Taniwha, helping Matt prep the gear while another batch of wide-eyed city workers clustered nervously on the deck. She recognised the pale skin, the expensive gear they’d use a couple of times, their phones clutched like lifelines back to the world they could only escape for a day. Their eyes held the same desperate hunger she’d once felt, that ache for something real beneath the artificial glow of urban existence.

“First time diving?” Naia asked a woman whose designer wetsuit in her gear bag still bore price tags.

The woman nodded, and Naia saw herself months ago, terrified, hopeful, drowning in her own life.

“It’ll change everything,” Naia said softly, stowing the woman’s bag. “If you can just let go.”

But she knew the woman would return to her cornered life, with only photos to show for her short-term escape. The ocean couldn’t save every beaten-down office worker, but at least it had saved her.

Once anchored, Naia moved with practiced ease, checking equipment, explaining techniques. All the while, her eyes drifted to the water. This dive site was perfect for new divers, with a shallow protected area near the cliffs sloping out to deeper waters. Each clumsy dive reminded Naia of her own journey, but it was also a torment. She longed to slip beneath the surface, away from the noise of their nervous laughter, to find the perfect stillness that existed only in the depths.

During the surface interval lunch break, as the tourists clustered around a platter of sandwiches and fruit, Matt walked over with a smile. His fingertips brushed her wrist, a light touch, but electric in its familiarity. Their fingers intertwined briefly. A promise for later.

“You can go out for a bit now,” he whispered. “I’ll keep an eye on this lot. Just be careful. Don’t go too deep.”

“Thank you,” she breathed, already reaching for her gear.

Naia tugged on the tight-fitting wetsuit and pulled out her long fins and mask, slipping into the water with barely a ripple.

She swam away from the boat, away from the shore, above the deeper water. She floated while her heart rate returned to normal and then began her breathe-up, preparing for descent.

The tourist chatter on the boat faded to whispers, then silence as she tuned out everything but the ocean beneath.

With each exhale, her heart rate dropped. The familiar calm spread through her limbs like honey from the wild bees on the cliffs above. The space between spaces, the threshold where surface thoughts dissolved and something older, deeper, took control. An ancient genetic memory resurfacing from when the water was home.

She filled her lungs, folded at the waist, and slipped under.

Her body streamed downward, arms swept back, legs together, the long fins propelling her with economical kicks that barely disturbed the water.

At five meters, the pressure began its gentle squeeze, compressing her wetsuit, making her heavier.

At ten meters, she stopped kicking entirely and surrendered to negative buoyancy.

This was the moment she lived for, this free fall through blue space, dropping through liquid light, weightless as a prayer.

The everyday world above dissolved.

Time dilated, stretched, became irrelevant.

Her lungs compressed to half their surface size, then less, but the mild hypoxia brought clarity rather than panic.

Colours shifted in the filtered light, the brilliant blues of the shallows deepening to midnight indigo.

A school of two-spot demoiselles parted around her like living water. She moved through them without urgency, each movement deliberate and fluid.

The urge to breathe remained distant, only a whisper.

At fifteen meters, Naia turned and began her ascent, following proper protocol even in the grip of blue euphoria. The return to light was a journey through shifting veils of colour — purple to blue to turquoise to the brilliant white-gold of surface sun.

Her heart rate picked up slightly as lighter pressure allowed blood to flow back into her limbs, but the profound calm remained.

Naia broke the surface in a controlled exhale, no desperate gasping, no panic. She turned towards the boat and made the okay signal, touching her fingertips to the top of her head. Matt waved back from the deck, grinning at her pleasure as she prepared to dive once more.

Later that evening, Naia nestled into the crook of Matt’s arm, her damp hair still carrying the scent of open ocean, languid and content in the way that only hours in deep water could make her feel.

Around the table, the usual crew sprawled in mismatched plastic chairs — Jack, one of the skippers; Tui, a marine biologist who doubled as a dive guide; and Fred, a photographer whose underwater shots graced the walls of half the dive shops in Northland.

They sat on the deck of the Deep Sea Angler’s Club wolfing down plates of battered green-lip mussels and steaming fish and chips, alongside cold bottles of Steinlager.

“Saw a pair of bronze whalers cruising the stern section of the Waikato today,” Jack said in between bites. “Must’ve been four meters long, both of them. Gliding through those cargo holds like they owned the place. And the soft corals. Fred, the light was perfect. Pink and orange jewel anemones covering every surface.”

Fred grinned. “I got some good shots at Blue MaoMao Arch today, swirling schools of koheru in shafts of light. I’ll get them printed to sell in the dive shop.”

“We mostly stayed shallow today,” Matt said as he traced a lazy circle on Naia’s shoulder with light fingertips. “Decent group of beginners. Naia’s turning into quite the instructor.”

She nudged him in the ribs. “Just following orders, boss.”

He mock-groaned and the laughter of the group warmed Naia inside. Just a few months ago, she’d been a nervous tourist clutching rental gear. Now these locals accepted her as one of their own, and this place was beginning to feel like somewhere she could belong.

Tui took a long sip of her beer and then spoke, her tone serious. “I was down at Northern Arch, part of the biodiversity survey at depth, around thirty-five to forty metres. I was photographing these massive elephant ear sponges, absolute beauties, when I noticed something in the rock face. A gap, maybe three meters wide, cutting back into the cliff. It wasn’t on any of our survey maps.”

Naia felt Matt’s arm tense around her shoulders.

“There was a current flowing out of it, and the water was colder, bluer…” Tui’s voice grew soft and her eyes focused into the distance as if she could see back into that secret place.

“But it wasn’t just cold. It was alive. The water moved like… like it breathed. And the light. It looked like the light was coming from inside the rock, not filtering down from above. Blue-white, like captured lightning, pulsing in rhythm with the current.”

Tui shook her head, as if trying to dislodge the memory. “Maybe it was bioluminescence, but it wasn’t plankton or jellyfish. It was the water itself, glowing from within.”

“There’s nothing down there,” Matt said sharply. “You must have been narked at that depth.”

“Or it was a way into the Cathedral.” Fred’s tone was quiet, almost reverent.

“What’s the Cathedral?” Naia couldn’t help herself, the question escaping her lips before she could stop it.

The others exchanged a look that carried years of shared knowledge and unspoken warnings.

“Legend,” Jack said firmly, as he picked nervously at the label on his beer bottle. “Just a bloody legend.”

“What kind of legend?” Naia pressed, curiosity overriding the growing tension at the table.

Matt pulled away from her, but he stayed silent as Tui explained.

“Some say there’s a massive underwater cave system deep beneath the islands. Deeper than any diver has ever been, or could possibly go. There are local Maori stories about a sacred place where the spirits of the drowned gather, where the light coalesces into something rare and beautiful. Where the ocean keeps its secrets. To see it is to—”

“That’s enough,” Matt cut in. “It’s a myth, and a deadly one, at that.”

He pushed his chair back. “Naia, come with me. I want to show you something.”

It wasn’t a request.

Matt guided Naia away from the table, his hand warm in hers as he steered her out of the club toward the back of the marina complex.

Behind them, Jack launched into a raucous story about last week’s fishing tournament, clearly trying to change the subject.

“What was that about?” Naia said as Matt walked out toward a section of the waterfront she’d never explored. “What’s the deal with this Cathedral?”

“This way.” Matt led her around the back of the dive shop, where a narrow path wound between towering pohutukawa trees.

The lights and the laughter from the club faded behind them, replaced by the whisper of wind through native flax and the distant boom of waves against the headland.

Matt stopped in front of a maintenance shed tucked into a grove sheltered by overhanging cliffs. “We keep this hidden. Away from the tourists.”

The obvious question — why? — died on Naia’s lips as Matt unlocked the weathered door.

Inside, he fumbled for a moment before a soft light bloomed from within a carved pāua shell, its iridescent surface catching and amplifying the glow.

Naia’s breath caught.

The shed wasn’t for maintenance storage.

It was a shrine.

Photographs lined the walls, dozens of them, some recent, others faded with age and salt damage, some in colour and some black and white.

Faces smiled out from behind diving masks or raised beer glasses, eyes bright with the particular joy that came from spending days beneath the waves and on the ocean. But there was something final about the way they were arranged, something that spoke of memorial rather than celebration.

Against one wall, a carved piece of kauri wood held a collection of objects, like a rustic altar to an ancient sea god. A diving mask, its tempered glass spider-webbed with cracks and fused with barnacles. A speargun tip, its steel shaft corroded into something resembling delicate lace made of rust. A pair of lead weights melted and seared together by what could only have been incredible heat — or incredible pressure.

“As much as we love the deep water, Naia, it is not our domain.” Matt reached out to touch each object, moving through them like rosary beads. “Depth is a debt. Oxygen is the currency. And those who forget pay the ultimate price.”

The pāua-shell light cast shifting patterns across the weathered photographs, making the faces seem to move, to breathe. Men and women who’d shared her love of the deep blue, and lost their lives to it.

“Some were accidents — equipment failure, medical events, simple bad luck. But others…” He gently took her hand and placed it atop the fused lead weights.

The metal was impossibly cold, unnaturally heavy. Grief made solid. “Others went looking for something that shouldn’t be found.”

He turned to face her. “The Cathedral isn’t a legend, Naia. It’s real. It calls to those who love the depths, and its hunger knows no end.”

The light in the pāua shell seemed to dim, or maybe it was just Naia’s vision adjusting to the growing darkness outside. Through the small window, the marina lights twinkled like fallen stars, peaceful and safe and impossibly far away.

“Promise me,” he whispered. “Promise me you won’t go seeking the Cathedral. No matter what you hear, no matter how the deep water pulls you.”

She stepped into his arms, pulled him close, put her head against his chest so she didn’t have to meet his eyes. “I won’t go looking.” The lie tasted of salt and inevitability. “I promise.”

In the early hours of the next morning, Naia walked outside to the deck and gazed out towards the islands. Somewhere beneath those dark waters, something vast and luminous waited — not just the Cathedral, but the truest version of herself, the one that could only exist in that impossible blue light. She practiced her breathing, slowing her heart rate, and felt the pull of the water, drawing her not down but home.

Behind her, through the thin hostel walls, she could hear Matt, restless in his sleep, his unconscious murmurs sounding almost like prayers.

***

Three weeks later

Naia slipped away from the dive boat while the tourists clustered around the crew for their lunch break. Matt was working in the dive shop on shore today, and as Jack was the skipper, he’d quickly nodded at Naia’s request for some alone time. This was a more experienced group, and they were moored near Northern Arch, over the deeper waters.

As Naia finned towards the arch, she calmed her breathing. It was faster than usual from the anticipation that had been building since the night when she had first heard of the Cathedral.

Three weeks of careful diving, of staying within recreational limits, of pretending that Tui’s words hadn’t lodged themselves in her consciousness like a splinter of blue light.

Three weeks of lying beside Matt, listening to his peaceful breathing while her pulse raced with the thought of that impossible luminescence flowing from a crack in underwater stone.

Beyond Northern Arch, the sea floor dropped away in shades of blue. Even from the surface, Naia could see the rich ecosystem that thrived here in the temperate waters. Pink and orange jewel anemones clustered in every crevice, schools of blue maomao swirled through the arch like living ribbons of silver and indigo, and powerful kingfish hunted in the depths.

Naia adjusted her mask and relaxed, preparing to dive.

With each long, controlled exhale, her pulse dropped toward the meditative rhythm that marked the boundary between surface consciousness and the deeper state that free-diving demanded.

Her heart rate slowed, her peripheral vision sharpened. She was becoming something older, something at home in the blue depths.

She folded at the waist and slipped beneath the surface, her long fins propelling her with economical kicks, until she could surrender to the free fall through blue space.

The massive stone walls of the arch curved away on either side, carved smooth by millennia of current and wave action. The volcanic rock was alive with colour, jewel anemones swaying in the current like underwater flowers, purple and white sponges carpeting the walls, some of them massive barrel formations older than human settlement in these islands.

A school of trevally parted around her, their silver flanks catching filtered sunlight as they reformed in her wake. A massive snapper cruised past with lazy confidence, its scales catching the light like hammered bronze, before gliding away into the deeper blue.

Twenty-five meters.

Thirty.

The pressure squeezed her wetsuit tighter against her body, compressed her lungs, but Naia felt no urge to breathe. Her body found its rhythm in this liquid realm, her blood shunting from extremities to core, her heart rate dropping to something that barely qualified as life by surface standards.

Elephant ear sponges appeared on the deeper walls, their surfaces rippling in the current as they filtered microscopic life from the water, patient architects of calcium and living tissue that had been growing here for generations. Some were larger than dining room tables, their yellow and orange surfaces creating underwater gardens of impossible beauty.

Thirty-five meters.

Colours shifted in the filtered light, brilliant blues giving way to deeper indigo and purple. A stingray materialised from the blue distance, its wing-tips barely moving as it hung motionless, feeding in the current. Then more of them, stacked up in the arch, like a squadron in perfect formation, wings barely stirring.

Forty meters.

This was deeper than Naia had ever been alone, deeper than she should dive without supervision. But her body felt strong, her mind clear. The narcosis that should have clouded her judgment instead sharpened her focus to a laser point of awareness.

And there it was — just as Tui had described.

A crack in the rock face, perhaps three meters wide, cutting back into the cliff. A current flowed from the opening, carrying water that was colder and somehow more alive than the surrounding sea.

Blue-white radiance pulsed from within the crack, synchronised with the flow of the current. But it wasn’t reflected sunlight or bioluminescent plankton. The light was generated from within the rock itself, as if the water glowed with its own inner fire. It pulsed in a rhythm that matched her slowing heartbeat, calling to something deep in her cellular memory.

Naia hung suspended in the water column, forty meters down and completely alone, watching light that couldn’t exist paint the sea in colours that had no names. Mild hypoxia wrapped around her consciousness like silk — making every sensation more vivid, every moment stretch into crystalline clarity.

She should surface. Return to the boat. Pretend she’d never seen this impossible light flowing from the bones of the earth.

She finned gently toward the crack.

At the threshold, Naia paused and looked up. High above, sunlight danced on the surface, a world away from the deep.

She thought of Matt’s fingertips tracing patterns on her skin, his voice whispering in the darkness of the shrine. ‘Promise me.’

The light pulsed again, brighter now, and Naia slipped inside the crack.

It wasn’t a choice anymore. It was inevitability, written into her DNA by millions of years of mammalian evolution, by the ancient part of her that remembered when the ocean was home and the air above was an alien place.

Naia finned on, propelling herself through the crack.

The rock walls enveloped her, worn smooth by eons of current flow, narrow enough that she could touch both sides with outstretched arms. As the current pulsed inward, it carried her deeper into the bones of the volcanic island.

The pressure should have been crushing, her wetsuit compressed paper thin, but Naia felt lighter than air. The light intensified as she was drawn deeper, no longer just emanating from the water but seeming to pulse from the rock walls themselves. The stone had taken on a translucent quality, as if lit from within by some impossible fire.

The passage opened out.

The Cathedral cavern stretched away into infinity, its walls curving upward and outward beyond the reach of her vision, disappearing into luminous darkness shot through with veins of living light.

Stalactites and flowstone formations hung like frozen waterfalls, their surfaces gleaming with the same inner radiance that suffused the water. The entire cavern glowed with bioluminescent fire — green and white and cobalt shifting and swirling in patterns that seemed almost like a forgotten language. The light moved in complex geometries of waves and spirals.

Schools of fish unlike anything she’d seen in the outer waters moved through the glowing medium, translucent creatures made of the same light that illuminated them. Some were familiar shapes rendered in luminescence: angelfish and wrasse and small sharks that glowed like living constellations. Others defied classification entirely, jellyfish-like beings that pulsed with their own inner rhythms, eel-like creatures that wrote sentences of light across the cavern walls with their movement.

Naia floated in the centre of the impossible space, her body weightless as her mind expanded beyond the boundaries of individual consciousness. Some part of her knew that narcosis had a deep hold now, but the euphoria was enlightenment rather than intoxication. She was seeing the world as it truly was, stripped of the illusions that made surface life bearable.

She understood now why others who sought this place had never returned.

They had evolved beyond the need for air, beyond the crude matter of terrestrial existence. They had become part of this flow, part of the living ocean that connected every drop of water on earth into a single vast organism.

A profound sense of coming home flooded her chest as Naia floated in the centre of liquid light. The last of her surface fears dissolved into the eternal blue.

This was where all the deep currents led, where every breath had always been meant to end. This was peace.

This was where she could let go.

Author’s Note

This story has a long personal history.

In March 2000, when I turned twenty-five, I was burned out and resigned my IT consulting job in London. I flew to Perth, Australia and spent months travelling, camping in the outback and exploring the country, as well as enjoying the Sydney Olympics.

I learned to scuba-dive in Fremantle, Western Australia, and my first PADI Open Water dives were on Ningaloo Reef further up the coast. I spent time on scuba-diving live-aboards on the Great Barrier Reef and dived at various places on the east coast of Australia.

By December 2000, I was ready to head back to the UK to start a new phase of my life, but I decided to travel around New Zealand first.

I flew into Auckland and immediately headed north, up to Tutukaka, to dive the Poor Knights Islands.

That first day on the boat, we saw whales lunge-feeding, pods of dolphins, and gannets dive-bombing into whirling balls of fish. Later that day, I saw blue maomao and schooling koheru in the arches of the Poor Knights. And I fell in love with the boat skipper, also one of the dive instructors!

In the months and years after, I dived the Poor Knights Islands many times, and became a PADI Dive Master. I even won an award for underwater photography, which you can see at www.jfpenn.com/koheru. That was back in the days of film cameras, even underwater!

I never free-dived, but I watched many of the free-divers with their long fins descending into the deep. I listened to them talk about how it felt to be so free. I longed for it and sought that euphoria myself.

While you’re meant to always dive with a buddy, sometimes the experienced divers would head off alone. One day, I had the chance to do the same.

I was nervous and exhilarated as I descended alone to around forty meters, beyond where I should have gone.

I still remember the sheer joy of it. I felt the pull of the deep and considered staying down there, just breathing until there was no breath left.

That moment of consideration scared me deeply, and I realised I was suffering nitrogen narcosis, hypnotised by the beauty around me and forgetting how dangerous it was to be so deep, especially alone.

I checked my air and began my slow ascent.

I never dived alone again.

In 2023, I watched the documentary The Deepest Breath, which features the Blue Hole in Dahab, Egypt, where I also once dived. The idea for this story was born from that memory resurfacing, and written in honour of my many wonderful dives at the Poor Knights Islands.

I absolutely encourage safe scuba-diving and safe free-diving. Just make sure you follow all safety rules and precautions.

You can dive the Poor Knights Islands marine reserve with Dive! Tutukaka. Find out more at diving.co.nz.

If you’d like to safely free-dive, there are courses at freedive.co.nz.

I married the skipper, but (perhaps unsurprisingly) it didn’t last, and we divorced a few years later. I wrote the poem on the next page, “Ocean Meditation,” when I was ready to take my wedding ring off. It’s a pantoum, a verse form in which certain lines repeat in a pattern, and it echoes elements of this story.

You can listen to a solo episode of my Books and Travel Podcast where I talked about scuba-diving and the wonder of traveling beneath the waves at:

I’ve written about other memorable dives in some of my other fiction. In Stone of Fire, Morgan Sierra recalls a dive at the Moeraki Boulders while inside St. Mark’s Basilica. In Deviance, O’s memory of an encounter with an octopus plays an important part in the story, and The Dark Queen features a dive to a submerged Egyptian city.
