Gwen Proctor has always been willing to do anything it takes to protect her kids. But there are some things even she can't protect them from. When a violent incident at Connor's school brings the press to Gwen's doorstep, she agrees to take a case out of town hoping to keep her family out of the crushing media spotlight.

The case is that of a missing girl, last seen getting into a truck with a stranger before disappearing. Gwen has a reputation for finding those who are lost, but this time something is wrong. Her instincts are off, and every clue she uncovers only raises more doubts, not just about the missing girl and the circumstances of her disappearance, but also about the fragile safety Gwen's created for her family.

The closer she comes to uncovering the truth, the more she unwittingly puts those she loves at risk. Someone from Gwen's past doesn't appreciate the new life she's built for herself and is willing to do anything it takes to tear it apart. Except this time it isn't Gwen in the crosshairs, but her partner Sam. Without her instincts to rely on, how can Gwen protect those she loves against an enemy she never sees coming?
