ANYTHING by Holly Black. Especially Valiant and Tithe. Two great books.
Oh! And also, even though they aren't exactly novels, I suggest checking out the colored fairy books, by Andrew Lang. They're all fairy tales, not necessarily about fairies. That said, theyve's got a lot of stories about the fae (though in their more traditional gory, scary forms), and are overall a great read. I know there's a blue fairy book, and a red, but I don't know about others.
