Sunday morning service at Mariston's Second Baptist Church usually brings grace. For Detective Sara Wren, the discovery of a mutilated body-the second in a week-is the continuation of a nightmare.
Along with the body, Mariston's first serial killer has left a gruesome message suggesting Wren's team overlooked a previous victim. Something vital escaped them, and time is running out for the next person on the list.
The search pulls Wren into the dark corners of a mystery the river town thought it had drowned decades ago. But when the killer turns his sights toward the detective's family, the investigation becomes a desperate, personal hunt.
To catch a predator who anticipates her every move, Wren must channel the girl she used to be-the one who knew how to survive when everything else was lost.
