Query: A good book, but kind of perverted

I really, really liked the main topic in this book and it was so intriguing. Cormier is a really good author and I love so many of his books. This is one of the best by far. But one letdown that I didn't enjoy was how much perversion there was in it! It was so disturbing sometimes. I almost wanted to stop reading it after a certain point, but I didn't because the story was too good. So, too much nasty stuff, but a great story.
