I Don't Want to Kill You

The final book in the "John Cleaver" trilogy by Dan Wells, following I Am Not a Serial Killer and Mr. Monster.

John Wayne Cleaver is still not a serial killer, because to be a serial killer you have to kill people. Of course, his first action after successfully defeating Agent Forman was to use his cell phone to contact one of his associates and announce that he plans to kill her - even though he has no idea what she might be able to do to him, or force him to do to his family...

What's more, he wasn't expecting Nobody to come with backup.
