Xanth! And the Little House books, I still enjoy reading them. In adult fiction I am amazingly fond of Amanda Quick. (Jayne Ann Kretnz' historical romances) Yes, they have a formula. Yes, she uses some of the same tricks over and over, but they are witty and hilarious. I read them over and over.
I also still read HP fanfic on occasion. It's fun.
