My Friend Dahmer by Berf Backderf only sits on my shelve until I book talk it just once. My students are fascinated when I tell them that the book is based on a real boy who grew up to be a real man who murdered people. They only know of serial killers from TV and the movies. I get the “pleasure” of introducing them to a real life psychopath. It creeps me out a bit that this is such a popular book, but students love to read it.
