I have mixed feelings about this book. I've already recommended it to several people, and I can think of loads of other people I know who will enjoy it. The voice is super-real feeling, and it's funny (yay!), though perhaps a bit too self-conscious at moments. But the big climax happens way at the end of the book and while I suspected that something akin to the thing that happened would happen, I'm still not convinced that was the right time for the thing to happen. This is probably a personal preference thing, so your results may vary. Though, on the other hand, if it happened earlier on (such as halfway through), it would inevitably be compared to another boarding school book. So, there's that. 
 Basically, Winger is quite good, the sports elements (rugby in this case) were out-freaking-standing (yay!), and I think the gross-out humor will really click with its intended audience. But still... I caught onto the thing that happens near the end early on so that colored my enjoyment for a couple hundred pages. I recommend Winger but have complicated feelings about that one plot structure thing. 
 By the way, I know a lot of people hate the cover, but I love it in all its grossness--it totally works for me for the story and the back flap is badass.
