What are some good fiction books for a 15yr. old female teen?

I love to read and was looking for some good fiction books. I don't care for romance based books very much; I like science fiction, fantasies, mysteries, and adventure stories. I've read Sherlock Holmes, Artemis Fowl, Alex Rider, Maximum Ride, Lord of the Rings trilogy, Hardy boys, Nancy Drew, Narnia, and more that I currently can't remember. Any suggestions?
