Query: Pure, exploitative violent pornography

I must admit that this novel is well written, and builds at a nice pace. However, if you get to the final chapter (which is one of the most disgusting, revolting things you are likely to read in a mainstream novel), you will be left feeling filthy and in need of a shower. The violence in this book is just way too over the top, and in the wake of the Columbine tragedy, I believe is very irresponsible to release such a piece of fiction; any unbalanced teenager who reads this just might flip his lid. This thing is dangerous. I can't remember the last time I read a book and was this physically AND emotionally REPULSED.
