HE'S A KIDNAPPER. BUT SHE'S THE REAL MONSTER . . .

Hazel is twenty-seven, and her life is falling apart. As an amateur mycologist - someone who studies mushrooms - Hazel's hobby takes her to some dark places, but following a traumatic divorce she reluctantly finds herself back in her childhood home in the shadow of the sprawling Idless wood. To start rebuilding, she takes the plunge and arranges to meet her estranged sister Cathy; she also bumps into Suzie, an old school friend with whom she shares a dark childhood secret.

But then Hazel meets Andrew, who claims to have rare fungi growing in his old farmhouse. Lured out into the wilderness by curiosity and no little professional ambition, Hazel is trapped by Andrew, shut in the basement with no help for miles around.

As Cathy and Suzie desperately begin the search for her, Hazel starts to feel that something darker and even more terrifying than Andrew resides in that farmhouse. But is the power living in the dark with her or . . . much, much closer?
