Good books?

If you have already read Tom Sawyer, You might also try "huckleberry Finn", also by Mark Twain. Another good book is "1984" or "Animal Farm", both by George Orwell. I think I read them at your age. One other one I would recommend is "Watership Down". I'm sorry, but I can't remember the authors name. But, give one of these a try. It sounds like you have been reading some great books.
