In the most inhospitable place on Earth, the deadliest threat isn't the desert—it's the people who think they can escape it.

Casey Thornton fled England to escape her past, trading Somerset's damp caves for Death Valley's endless horizons. As an adventure guide at the ultra-luxury Desert Sanctuary resort, she leads wealthy guests on carefully controlled wilderness experiences, maintaining the illusion of danger while keeping them safe from the desert's true brutality.

But when a catastrophic storm traps the resort's latest guests—six strangers with secrets as dark as her own—the carefully maintained boundaries between civilization and wilderness collapse. Cut off from the outside world, with no rescue coming and resources dwindling, the veneer of civility cracks to reveal something far more terrifying than the harsh landscape beyond the glass walls.

As temperatures soar and tensions escalate, Casey discovers that some guests didn't come to the desert seeking adventure. They came to disappear. And they'll do anything—betray anyone—to ensure their secrets stay buried in the sand.

With each hour, the situation grows more desperate. The storm shows no sign of ending. Communication is impossible. And one by one, people start dying in ways that can't all be accidents. Casey must use her knowledge of the unforgiving terrain and her own hard-won survival instincts to protect the innocent—even as she confronts the trauma that drove her to this desolate place.

In Death Valley, the lowest point in North America, Casey will face the ultimate test: survive the night, or become another cautionary tale swallowed by the desert's indifferent vastness.
