What would be a good adult book for a teen to read?

Anything romance. Though nothing with sex scenes or that are too racy. I want something different from all the teen/young adult novels. They're the same exact thing over and over again. So do you know anything? I'm ok with horror, mystery, comedy, as long as it has alittle romance. And like I said, nothing too racy & no sex scenes please. Thanks. :)
