When former FBI agent Cate Wilde moves back to Widow’s Island, she envisions a simpler life than the one she had in law enforcement. But Cate’s past has a habit of catching up with her. When she receives a mysterious package containing a child’s mandible, she finds herself thrust back into action. The mandible leads Cate to an unsolved case she worked seven years ago—the kidnapping of a three-year-old girl. At the time, Cate suspected the girl was kidnapped by her overprotective father. But after they both vanished, the case went cold.
