She's either being stalked or losing her mind.

A job at a camp in the rustic and often rugged landscape of West Texas offers Maribel Montgomery a chance to escape both, especially if she makes sure no one knows where she's there.

But when the body of a woman washes up in the river on her first morning, her hope of a safe place to start over are swept away.

The suspicion she's being watched follows her to her new home, and Maribel is forced to take a stand or keep running. Does she have the courage to face the danger stirring at the Pool of Siloam Camp?

If she doesn't, another girl might die.

If she tries and fails, it could be her.

Circumstances force her into the acquaintance of Conner Pierce-a man with secrets of his own. Can Maribel risk working with him in order to save the next victim and find a missing girl?

Or is he the killer?
