In actuality, this is a very sweet story about a 17 y.o. suffering from OCD. I think the first sentence probably puts some readers off (on goodreads, anyway), but if it makes more teenaged boys read it, I'm all for it. Karo does an excellent job channeling a teen boy (maybe because he isn't too far from it himself?) and the social agonies of high school. And then there's the problems of seeing a psychiatrist, trying cognitive behavioral therapy, and medication.
I couldn't help wondering how much of it was autobiographical, and thinking how very sad for Raboteau if it were true.
One thing only bothered me - a character dies in a way that I saw rebutted on Mythbusters recently.
The wolf-man bond has some interesting repercussions, especially when it comes to hierarchy and sex. I don't want to give too much more away than that (and I have to say the reviews I read were good about not giving spoilers, either, except for the repeated use of words like powerful and brutal).
Do NOT read the goodreads.com reviews, they are almost all hugely spoilerific.
