After leaving the NYPD following her abduction by serial killer Blake Bram, Shana Merchant hoped for a fresh start in the Thousand Islands of Upstate New York. Her former tormentor has other plans. When the decades-old skeleton of Shana's estranged uncle is uncovered, Bram issues a challenge: Return home to Vermont and solve the cold case, or the blood he spills next will be on her hands. As Shana interviews members of her family and the community, mining for secrets that could help her solve her uncle's murder, she begins to realize how little she remembers of her childhood. And when Bram kidnaps again, leaving a trail of clues Shana alone can understand, she knows his new victim will only survive if she wins the psychopath’s twisted game.

Thirteen months ago, former NYPD detective Shana Merchant barely survived being abducted by a serial killer. Now hoping to leave grisly murder cases behind, she has taken a job in her fiancé's sleepy hometown in the Thousand Islands region of Upstate New York. But as a nor'easter bears down on her new territory, Shana and fellow investigator Tim Wellington receive a call about a man missing on a private island. Shana and Tim travel to the isolated island owned by the wealthy Sinclair family to question the witnesses. They arrive to find blood on the scene and a house full of Sinclair family and friends on edge. As the gale intensifies outside, Shana starts conducting interviews and discovers that the Sinclairs and their guests are crawling with dark and dangerous secrets.
