New York Times bestselling author Kay Hooper takes readers on a terrifying manhunt for a serial killer even the Special Crimes Unit may not be able to stop.

Dani Justice knows all about monsters. They haunt her dreams—and her life. But she never expected to find herself on the trail of a real flesh-and-blood predator so cunning that he’s eluded the best law enforcement could send against him; and so deadly that he doesn’t hesitate to kill even a senator’s daughter. Or a cop. Dani doesn’t want to hunt this killer, but she doesn’t have a choice. She alone commands a weapon powerful enough to stop him. And she knows something even Bishop of the FBI’s Special Crimes Unit doesn’t know. Dani knows how the hunt ends. It ends in fire. And blood. And death. What she doesn’t know is who will survive.
