Life is going well for two of the FBI's most accomplished Agents. Agent Max Prescott is well-respected in her field, with a stellar reputation and six years of service under her belt. Agent Dani Prescott's reputation is almost on par with her wife's, although she's only been with the agency for a few years. Despite their Superior's concerns about having married couples work the same assignments, Max and Dani have proven themselves as an elite team. When five teenage girls go missing from a small Oregon community, Max and Dani are called in for an undercover operation like none they've executed before. The devoted couple has portrayed themselves as everything from sisters to rivals, but this case is different. This time, they'll be passing themselves off as mother and daughter. While Max finds herself teaching, and studying, a High School English class, Dani is chosen to join the students. Parading around with a bunch of seventeen-year-old's is not how Dani envisioned spending her first wedding anniversary. Within days of their private celebration, a girl she's befriended becomes the sixth to go missing. Determined to find, and stop, whomever is responsible for the disappearances, Dani delves into the strange world of teenagers. Will Max and Dani be able to locate the missing girls and return them to safety? Or, will Dani become the seventh victim of a diabolical mastermind, hell-bent on purging the town of the sins of youth?
