When Detective Winston Radhauser's phone rings in the middle of the night, he knows something terrible has happened. On this night, a homeless man, rummaging for food in a local dumpster, finds the body of a severely beaten young woman. On scene, Radhauser estimates the victim to be in her early twenties. He's overcome when he learns the forensics reveal she is the girl whose disappearance has haunted him for three years—Ava Cartwright.

In broad daylight, Ava's bicycle had been found parked with the kickstand down near a wooded area. Search parties inched their way through every portion of those woods, the neighborhood, nearby Lithia Park, and along miles of railroad tracks, but there was no sign of the little girl.

Where has she been all this time? And why was she dumped on the eve of her thirteenth birthday? There must be something, some tiny detail, he missed that will give him a lead. This time, Radhauser won't quit until he finds it.
