Pig Island [EPUB ebook] 

A born skeptic, journalist Joe Oakes believes everything has a rational explanation. He makes a living exposing supernatural hoaxes, but when he visits a remote Scottish island and a secretive religious community accused of Satanism, everything he thinks he knows is overturned. What has happened to Pastor Malachi Dove, the leader of the community? Why will no one discuss the strange apparition seen wandering the lonely beaches of Pig Island? The answers will lead Oakes to a confrontation and a bloody aftermath that force him to question whether he might not be responsible for a terrible crime. In this compulsive and disturbing novel, Britain’s "Queen of Fear" dares her readers to face their terror head-on.
