Journalist Joe Oakes makes a living exposing supernatural hoaxes. A born sceptic, he believes everything has a rational explanation. But when he visits a secretive religious community on a remote Scottish island, everything he thought he knew is overturned.
Questions mount: Why has the community been accused of Satanism? What has happened to their leader, Pastor Malachi Dove? And perhaps most important, why will no one discuss the strange apparition seen wandering the lonely beaches of Pig Island?
Their confrontation, and its violent and bloody aftermath, is so catastrophic that it forces Oaksey to question the nature of evil, and whether he might not be responsible for the terrible crime about to unfold.
In this compulsive and haunting novel, Mo Hayder dares her readers to face their fears head on and to think about the unspeakable things people can do to each other.
