FBI special agent Zoe Spencer uses skeletal remains to recreate the faces of murder victims through sculpture. Though highly scientific, the process is also sensitive and intimate; she becomes attached to the individuals she identifies, desperate to find justice for each. As Zoe examines old remains, she sees a teenage girl looking back at her—the victim in a cold case from over a decade ago. Zoe wants nothing more than to tell this young woman’s story and to bring her killer to justice. Zoe’s case leads her to the victim’s hometown and to homicide detective William Vaughan, Zoe’s on-again, off-again lover. As the two become more involved in the case, they quickly realize that it isn’t as cold as they first believed: someone’s still out there hunting women. And with more women gone missing, time’s running out. Can they work together and stop this madman before he kills again?
