Harry Potter is great fun for both kids and adults. I love them. The juxtiposition of the normalcy of shopping for school supplies with the fact that the school supplies in question are things like magic wands and books that have moving pictures, for example, is delightful. I am also eagerly awaiting the next one. For adults who like fantasy, try "Ship of Magic" by Robin Hobb, and the rest of that series. It was recommended to me by a very down-to-earth lady sailor who said it was the best book she ever read, and at one quarter of the way through it, I am inclined to agree. It's very realistic, with just enough fantasy to let you know you're in an alternate world.
