An all-new stand-alone novel from #1 internationally bestselling author John Connolly, The Castle is a gripping thriller where paradise is an illusion and security comes at a deadly cost.

The Castle is a safe haven, a gated community in a nation troubled by the war in Vietnam, political assassinations, and the growing shadow of Watergate. For the disillusioned publisher Hamer, it is an escape from a world that has disappointed him. But something is very wrong in the Castle. A teenage boy has gone missing. There are thefts, threats, shootings. Hamer has begun to fear the Castle may not be so safe after all, and he and his neighbors are the targets of a conspiracy with a single purpose: to destroy five families and punish them for the sins of their children. And one of those families could be his own. Now Hamer must confront the dark truths behind the Castle, truths that lie terrifyingly close to home. Because security requires sacrifice. And blood will out.
