People are inexplicably disappearing from Chicago prosecutor Jess Koster’s life. First her mother vanished without a trace eight years ago. And now a client, the victim of a brutal, sadistic rapist, is also missing. Someone is disrupting Jess’s neat, ordered existence with chaos and terror. And from the shadow of her past, a maniac is watching her when she goes to work and waiting for her when she goes home, stalking her until there is no one Jess can trust. And she feels with blood-chilling certainty that her mysterious tormentor is perilously close and that the next person to vanish from the face of the Earth will be Jess Koster.
