Davis Moore is a fertility doctor in Chicago specializing in reproductive cloning, a controversial and closely regulated new practice, when his seventeen-year-old daughter is brutally raped and murdered. The case is investigated but never solved. Months later, Moore retrieves her belongings from the police, and finds among them a vial containing the killer's DNA. Tormented by grief, Moore entertains a monstrous thought: the possibility of cloning not his daughter but the man who killed her. How far would you go to look into the face of your daughter's murderer?
