Genevieve Callow, the FBI’s top criminal profiler, is growing tired of her constant race against the clock. A quieter life seems possible—until a hike in the woods around the town of Roxobel leads to the discovery of a victim’s body covered in runes on a bloody altar. Local law enforcement is outmatched and under-equipped, and the townspeople are terrified by the evidence of more rituals to come. First on the scene, Callow and her team are immediately assigned to the case, her short reprieve now interrupted by a cunning and sadistic killer who knows exactly who she is. The townsfolk are depending on Callow to solve the case before the bodies pile up because the killer has made one thing clear… He is far from finished.
