Darby McCormack was in high school when she first encountered the killer: someone murdered a woman in the woods where Darby and her two best friends were partying. His race to silence the witnesses was sure-footed and violent - but somehow Darby survived.

Twenty-five years later, Darby is a crime-scene investigator for the Boston Police Department, and a chilling case - a woman's late-night abduction - has her uncovering strange leads to missing women, past and present. As forensic clues lead her closer to a psychopath called the Traveler, Darby must finally resolve the nightmare of her past and come face-to-face with a killer who is determined to keep the missing - and the horrors they endured at his hands - from ever coming to light.
