I can't pick a favorite either but some of my top favs are:
The Techno-Pagan Octopus Messiah - Ian Muir Winn
Conversations With God - Neale Donald Walsch
Tuesdays with Morrie - Mitch Albom
Shampoo Planet - Douglas Coupland
The Harry Potter Series (Yes I said it!!)
I too read S.E. Hinton back in the day. Absolutely loved her stuff then. I've seen some titles recently that I don't recognize and have thought about picking them up.
