Book List for 9-12 year olds

My 10 yr. old needed a little more structure in her choice of literature, and while Nancy Drew is fun, we wanted to make sure she has some familiarity with other genres and literature. So my husband who is really behind most of the curriculum choices we make did some research mainly on amazon.com reading the reviews both good and bad for these books and came up with the following list. Neither of us have read all of these books although we have read some of them, so if any of you think any of them may be inappropriate for this age group, let me know. We bought most of them and I'm going to try to keep up with my kids' reading. It looks like a lot of fun. We want our kids to read at least one of the books listed in each genre.
