Returning home for her father’s funeral, Marnie learns a shocking revelation about her and her family. As she pieces together secrets an entire town wants to forget, it becomes clear that a dangerous legacy lives on, and she is the only one willing to stop it.​ Meanwhile, Detective DeLuca Greyson, a man haunted by his own past, is investigating a series of brutal murders. When he connects them to a twenty-eight-year-old mass murder in a remote rural town, his and Marnie’s paths cross. Though both seek the same killer, neither entirely trusts the other – especially since one wants justice and the other vengeance. But it is not long before the tables turn, and, as the extent of the killer’s depravity is revealed, both will stop at nothing to track down a man whose crimes have become very personal.
