Joe is insane. What makes him scary is that fact that he hides it well to others. When you think of a killer or stalker we don't think of the average Joe. I liked this book because it was real. It was written well and was funny. 
 I was also rooting for Joe. I wanted him to get the girl, which is crazy. 
 However I got bored. It just wasn't my cup of tea. Some will love this book, I didn't. I will still recommend it.
