Publisher's Synopsis
Boston CSI Darby McCormick finds a raving and emaciated woman hiding at the scene of a violent kidnap; the DNA identity search confirms that she was abducted five years earlier. Somehow she managed to escape from the dungeon in which she's been caged. Now with a teenage couple also missing, the clock is ticking for Darby as she hunts for the dungeon before anyone else disappears or dies. It soon becomes clear that a sadistic serial killer has been on the prowl for decades - and is poised to strike again at any moment.
