On Killing by Dave Grossman. I read the whole thing and was glad I did because I was able to better articulate to my friend who recommended it why it was such a horrible book. After reading the book I learned about the Killology seminars he gives to cops where he equates killing people to the enjoyment of having sex.
I wish I had known that before reading the book. These days I’ll read up on authors I want to read, ESPECIALLY non fiction books. Lesson learned.
Stephen King has a bunch of books divided into either short stores or longer novellas. So you can just read one or two then go back to it later.
