Dh and I both read and loved the Hobbit at this age. It is a great adventure story, and and he is reading it now with DD5. Phillip Pullman is good when they are a little oolder, I would say 9-10. I think she could handle the first couple of Harry Potter books. #3 would be a judgement call, and I would not let her read #4 untill about 9-10. I will have to look at the other young adult ficton we have when I get home for recommendations. WE are a big adventure story family, so that is mostly what we read.
