Oh, definitely Harry Potter! I would agree with you about being a classic, although I think you'd have a better argument for why. I just thoroughly enjoyed them! I hate to admit it to ya, but I'm not much of a reader. >.> But I couldn't put those books down! I was glued to them! I haven't read Lord of the Rings though, so I'm not really sure about that...
Debate's are always good, as long as feelings don't get hurt!
