Query: A book that makes you think

This book really makes you think. I finished it in a short amount of time, and I rememebr closing the book my head spinning. Usually after you finish a book you know right away if you did or didn't like it. I found with this book however that I was left so stunned that I could not even answer that question. It's about a boy who will be given everything he needs, money, a raise in his mother's paycheck, etc. for completing one act. Not just any act either, he must destroy something very dear to an elderly friend of his. I won't give away the ending, but this book leaves you wondering what would I do, and what is the right thing to do?
