Danielle Ross's life keeps slipping out of control. First she must abandon her education to take over her ill father's floundering detective agency. Then, while pursuing a new case, Dani becomes a victim herself. She awakens in a strange place and finds herself surrounded by eleven other people. Among them are a doctor, a dancer, a German submarine commander, and a former Death Row inmate--all clueless as to why they have been brought together. The culprit relentlessly insists they are united by one dark secret and that their lives depend on their confessing it. Can Dani find the link between these strangers before time runs out?
