When the trunk slammed closed, sealing her fate, a deep cold slithered into the center of Kennedy's bones. All she could do was pray that her attacker would leave enough of her for her family to identify . . . Kennedy Farmer, an experienced athlete, never returns after leaving for her usual running route through the dusty mountain trails of New Mexico. While the search for Kennedy begins, Detective Alyssa Wyatt and her squad face a terrifying new case when the body of a young woman, Rheagan Pembroke, is discovered in the desert terrain surrounding Albuquerque. Her wounds horrify even the hardened squad of the Albuquerque P.D.-and the case takes an even darker turn when they discover a polaroid stuffed into the victim's mouth, showing the body of Gunner Galveston, a murder victim from fourteen years ago. The culprit was never caught. As the team are taunted with gruesome packages and blood-curdling phone calls, it becomes evident that a serial killer-whose blood lust is increasing-has been operating in plain sight. To catch a killer, Alyssa and the squad need to understand the savage desires driving them . . . before Kennedy becomes another life taken at the hands of a psychopath.
