A chilling attack. A missing child. And a twisted killer driven to the very brink.
DI Louise Blackwell is still reeling from her brother Paul's murder when she is brought back from enforced leave and tasked with solving a strange new case - the slaughter of wild sheep at Cheddar Gorge, a place shrouded in mystery and folklore.
When a man is brutally attacked with a machete on the clifftop and a young girl disappears, Louise realises that the horror is just beginning. Rumours of a mythical presence near the gorge are spreading fast, and why is a local environmental cult resisting all attempts to solve the case? With the investigation into Paul's death about to be shelved and her bereaved niece to care for, Louise is under pressure - and running out of time. Can she find the girl and catch the kidnapper before her worst fears come true?
Drawn deeper into the dark and shocking truth behind the crimes, she soon finds she isn't the only one with secrets to hide.
