I think that I've read so many books that I don't have any favorites...but here goes:

The Hobbit
Pride and Prejudice
My Side of the Mountain
Harry Potter and the Socerer's Stone + Prisoner of Azkaban + Goblet of Fire
Journey to the West (original chinese version)
Summer of Riley

Yes, it weird because they're such a diverse group, and some are really for children, but I believe that a good book is timeless.
