Seduced in a bar, a young man finds himself in the clutches of a cult in this psychological thriller by the bestselling author of the DI Gravel series . . . Harry Gilmore meets a beautiful girl in a local student bar. The next thing he knows, he wakes up in a secure wooden compound deep in the Welsh countryside, where he is groomed by the leaders of a manipulative cult run by a self-proclaimed new messiah, referred to as the master by his followers. In addition, the medication Harry relies on is gone. When he begins to grasp the situation, Harry looks for any opportunity to escape the people who drugged and abducted him. But as time passes, he begins to question whether the master’s extreme practices and teachings are indeed the one true religion. With Harry’s life and mind hanging by a thread, a team of officers, led by Detective Inspector Laura Kesey, investigates his disappearance. But by the time they find him, will he be able—or willing—to leave?
