When Aria, a young girl with autism, goes missing, search and rescue expert Beckett Stolle ventures into the swamplands of Texas to track her down. When he finds the girl, she is alive, sitting next to a corpse painted in blood. Accusations fly, including suspicion that Aria was involved in the macabre murder. Beckett, however, fears this is the work of a notorious serial killer, turning his rescue mission into a hunt for a murderer. But every clue leads back to Aria, who has secrets of her own—something her psychiatrist, Jo Bellerose, sympathizes with on a very deep and dangerous level. As an ice storm descends on Texas, Jo partners with Beckett, a handsome ex-military outdoorsman, to prove Aria’s innocence and find the real killer before another victim is slain. The two get trapped in the wilderness, where their professional relationship morphs into something intensely personal. And the danger headed their way is one they never saw coming.
