Well-developed characters and an expertly paced plot that builds into a breathtaking conclusion.” —Publishers Weekly on Knockout (starred review) A serial killer is on the loose, and it’s up to FBI agents Dillon Savich and Lacey Sherlock to bring him down. They soon discover the killer has blood ties to an infamous and now long-dead monster. Savich and Sherlock are joined by agents Lucy Carlyle and Cooper McKnight, and the chase is on. At the same time, Agent Lucy Carlyle learns from her dying father that her grandfather didn’t simply walk away from his family twenty-two years ago: he was, in fact, murdered by his wife, Lucy’s grandmother. Determined to uncover the truth, Lucy moves into her grandmother’s Chevy Chase mansion. What she finds, however, is a nightmare. Not only does she discover the truth of what happened all those years ago, but she faces a new mystery, one that has been passed down from mother to daughter for generations. As the hunt for the killer escalates, Savich realizes he’s become the killer’s focus, and perhaps the next victim. Only Lucy can stop this madness before it’s too late.
