Lost

Tara Jean Dobbs was a Texas police officer until her friend Lucy Caldwell almost died on her watch. She's since left the force, left Dobbs Hollow, and vowed to never let a loved one down again. So when her best friend Andrea joins a seemingly harmless spiritual cult-only to disappear without a trace-Tara decides to find out what happened by becoming one of the Chosen herself.¿¿
Five months later, no one's heard from Tara, and FBI Agent Jacob Nolan is going after her. Taking a false identity, Jacob finds it surprisingly easy to play the part of Tara's boyfriend. But as they uncover the inner workings of the Chosen, they realize how much danger they're in. Because Andrea isn't the first follower to conveniently disappear-and they may be next.
