Now don't dismiss me as an airhead, but I recently really enjoyed reading the Harry Potter books (against expectations!) and would like to read something similar. I am not talking children's books, or school stories, and preferably not fantasy books either although if you know one that really fits the bill, you could mention it. What appealed to me about HP was the mentor/protege relationship between Dumbledore and Harry, and the fight for good over evil.
Anything to recommend?
