The Twilight Saga is an excellent series of books. Each book starts of slowly, in my honest opinion, but suddenly you get to a point where you just can't put it down. They are quite interesting. They are, of course, fantasy literature. I guess you need to ask yourself if that is the type of book for you. While they have the element of the vampires, they are also realistic in the relationship between Bella and Edward. Other than the fact that he is a vampire, their relationship/emotions seem very similar to those of high school aged children.
