In I Am Not a Serial Killer, John Wayne Cleaver saved his town from a murderer even more appalling than the serial killers he obsessively studies. But it turns out even demons have friends, and the disappearance of one has brought another to Clayton County. Soon there are new victims for John to work on at the mortuary and a new mystery to solve. But John has tasted death, and the dark nature he used as a weapon---the terrifying persona he calls “Mr. Monster”---might now be using him. No one in Clayton is safe unless John can vanquish two nightmarish adversaries: the unknown demon he must hunt and the inner demon he can never escape. In this sequel to his brilliant debut, Dan Wells ups the ante with a thriller that is just as gripping and even more intense. He apologizes in advance for the nightmares.
