Soon he will find there are fates worse than being buried alive, for in the abandoned mines and caves beneath Pintalba, there are ravenous teeth in the dark.
As a savage predator targets the group with hideous ferocity, Sam and his friends must fight for their lives if they are ever to see the sun again.
"The Cavern is a tense and compelling descent into subterranean horror, with characters you will care about in a setting unlike most fiction these days. I've never been a fan of caving, but having read this book, I'm staying above ground in the sunlight forever." - Alan Baxter, author of DEVOURING DARK and the ALEX CAINE SERIES
