I just discovered books I am interested in, and need to find more like the ones I have read?

My latest book, was the last in The Mediator Series which I enjoyed. I was very said, however, that the series were over, and was wondering if there were more like it. I enjoyed that series, as well as the book A Northern Light. I would like to find a combination of both though. Something that has a lot of romance and intimacy, but also has ghosts or maybe other science fiction items. However, I think what I enjoy most in what I read, is when two people (preferably 2 guys) fighting over the main character (preferably a girl.) I really want the book's main character to be a teenager. I do like mystery, but not a lot, because that just pisses me off. I really just want the 2 guys fighting over a girl thing, that involves intimacy and the characters being teens. Also, I would really like a book in a series... Please help me find a book I'm interested in!!!!
