A relentless FBI profiler hunts a vicious killer.

When old evidence turns up on a fresh corpse, ASAC Lincoln Frazer is determined it won't delay the execution of a convicted serial killer. But when more young women are brutally slain, it becomes clear - this new killer is intimately familiar with the old murders.

A dedicated emergency physician hides a dark secret.

Former Army Captain Dr. Isadora Campbell helped her mother conceal a terrible crime. After her mother's death, Izzy resigned her commission and returned to the Outer Banks to raise her rebellious teenage sister. But it doesn't take long for Izzy to suspect that someone knows exactly what she did, all those years ago.

If they work together, maybe no one else will die.

With pressure mounting to reopen the old case, Frazer will use any means possible to catch the killer. Thrust together during the investigation, he and Izzy find themselves reluctantly attracted to one another, and begin an affair. Meanwhile, the killer is much closer than they think. Izzy's confession of her secret drives Frazer away as he struggles with her deception. By the time he realizes he's fallen in love with the stubborn woman, the killer has her. Now the race is on to save Izzy and any chance of a future they might have together.
