They lead her to a macabre discovery in a Benedictine Monastery, and soon after she discovers a mummified corpse in a state park. ...for an eye There seems to be no pattern to these killings, except that each mimics a killing connected to something a younger Tempe experienced, or barely escaped. Someone is targeting her, and she needs to figure out why before they strike again. And then her daughter Katy disappears. Someone is playing a dangerous game with Tempe. And they won’t stop until they have taken everything from her... Electrifying, heart-stopping and compulsive, this is Tempe’s most personal and dangerous case yet...
