Cold Fear by Toni Anderson

Enigmatic and aloof FBI profiler Lincoln Frazer falls for a woman hiding dark secrets…

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.
After her mother’s death, former Army Captain Dr. Isadora Campbell resigned her commission in order to return to the Outer Banks to raise her rebellious teenage sister. But Izzy hides a terrible secret, and it doesn’t take long to realize someone knows exactly what she did, all those years ago.
Thrust together during the investigation, Frazer and Izzy find themselves reluctantly attracted to one another. The truth about Izzy’s past drives Frazer away as he struggles with her deception. The killer strikes again, and now the race is on to save Izzy from the same fate as all the other dead girls.
