Query: A subtle classic you've probably overlooked

The book is an amazing plunge into the human mind. The more you read, the more engrossed you become...Some of it is stomach churning, some heart wrenching...However, it feels too real for you to take comfort in saying: "It's only a book". Although a complete work of fiction, it is as real as any autobiography I've read. It is thought provoking, inspirational and has a depth that varies depending on the reader. A friend of mine read it and took a completly different meaning from it...He couldn't see what I saw so it's definately a disscusion book, one to share with your friends...My copy has been passes around and around and around and we still talk about it. I definately recommend this book, especially for teenage boys and philosophers.
