I received an advance ARC copy from the author and also purchased it.
Just like with Stephen King, Penn has the gift, to give her readers a heart pounding hellacious read, one that's well researched, puts you right in the pages, full of heart pounding twist and turns and leaves you begging for more.
It's really my type of book, due to the fast pace, it's action packed, full of suspense, tension filled, has you on the seat of your pants, an extra load of twist and turns and like the good very evil theme.
Penn's characters are amazing the good ones or the evil ones, they just come to life, making the story all that better and you're right they're in the midst of the action.
Especially with Catacomb, Penn brings to life the dark catacombs under Edinburgh, with an unlikely crew of Walker Kane the father, Laurel a librarian, Max a student come together to rescue Walker's daughter Emily, from a medieval evil sacrificially offering for the town's yearly prosperity and to know what happens you'll have to read it.
Definitely if you haven't tried J. F. Penn's books before, do yourself a favor and give her a try.
