The protagonist goes looking for the "Great Perhaps." I thought it might be something powerful and meaningful. But what it turns out to be is him hanging out with a bunch of other teens whose pastimes are drinking heavily, smoking, watching porn, and playing mean pranks. While it was horrible and stupid from the beginning, the real jaw-dropper was the lesson in oral sex. Really? In a book marketed to children? Do you know who is reading John Green books these days? It's all the way down to 5th graders, 10-year-olds. Mr. Green defends the scene by saying it is not erotic. Hello! That's worse! It is very casual. The receiver has barely even made eye contact with the girl, and afterward, he basically ignores her. Made me want to vomit.
