Try Lock and Key by Sarah Dessen, I've heard all of her books are good, but thats the only one I've actually read. I have a friend who really likes Chris Crutcher (sp?) books too. Hail Cesar is another one that's pretty good. Hope you find something good to read (:
Books about highschool? Well I read this one called Amulet... though it's a bit... dirtty. Basically its about this guy who finds an amulet that makes him invisible when he wears it, and, well... he's sixteen.
