The Killer Instinct series from New York Times bestselling author Cynthia Eden continues as an FBI profiler tracks a case that resurrects ghosts from his past… Ex-SEAL Tucker Frost knows that the world is full of evil. He saw it in the face of his own brother, Jason Frost, a cold, methodical, sadistic killer. A killer Tucker put down with his own hands in order to save Jason's final victim-Dawn Alexander, the only girl who got away from the infamous "Iceman." It's Tucker's up close and personal experience with evil that's made him perfect for Samantha Dark's experimental profiling division in the FBI. And when women start turning up murdered with the same MO used by the Iceman, Tucker is sent back to Louisiana to investigate. Ten full years have passed since the night that Tucker faced down his brother…and since he last saw Dawn, his one-time lover. But as Tucker and Dawn grapple with a desire that never died, they must also face the shared shadow from their pasts. Both have the same question-has Jason Frost come back from the dead to hunt again? And this time, will he succeed in killing the victim who got away?
