I Am Not a Serial Killer: John Cleaver, Book 1 by Dan Wells
After meeting somebody that knew they author, I decided to check out his first book. It is a book involving supernatural horror, which is usually something that I don't care much for. However, this is well grounded in reality and psychological exploration which makes it good. The protagonist, John Wayne Cleaver is obsessed with serial killers. He also has difficulty relating with people and has been diagnosed with psychological conditions. His family owns a mortuary in the small town, so they are familiar with deaths. After mysterious deaths take place in the town, he becomes intrigued. He chases things down and discovers that their peaceful next door neighbor is actually some sort of demon that can replace parts of his body with parts from other people. (The neighbor could also consume others in their entirety. However, he has fallen in love with his current wife and wants to continue it.) John regular does chores for the neighbors, and thus sees their peaceful existence. However, he also tracks down his activities to see the neighbor's demon behavior. Eventually, he helps to defeat the neighbor, but not after many people have died. It is an intriguing story as he finds out more about himself as he works to stop the crime.
