FBI agent Ren Bryce takes on her most heart-wrenching case yet when a father's work places his young daughter in terrible danger...

Every year Mark and Erica Whaley take a trip to Colorado to celebrate their wedding anniversary. This year they have more cause than ever to celebrate - they've finally been granted overnight access with Laurie, Mark's 11-year-old daughter from his previous marriage.

But their relaxing family break is shattered when they return from dinner in the hotel to find both Laurie and her 16-year-old babysitter, Shelby, missing.

Special Agent Ren Bryce will need to be at the top of her game to unravel the bizarre circumstances around this particular kidnapping. For it soon emerges that Mark has an awful lot to hide.

But Ren has her own battles to fight. Without a psychologist since hers was killed four months previously, she knows she's headed for a manic episode, and she not sure she wants to stop it.

The lives of two young girls are in Ren's hands. But she might need to save herself before she can save them.
