"A family of four murdered in their hotel room. A single mother and her boyfriend both stabbed to death. A sordid history of violent crimes, repeated over and over--but decades apart. Olivia Barker is a therapist with no connection to the murders. But she has heard things. Stories that keep her up at night. Details that only a killer would know. A killer who could be one of her patients. Olivia has no proof for her suspicions. But as the body count rises, so do her fears. A rock is thrown through her window; her car tires are slashed; a chilling message is scrawled on her bathroom mirror. Olivia knows she's getting closer to the truth. But the truth could be the last thing she'll ever know..."--Back cover.
