I just finished this book that I started Wednesday. It's called "Tithe," by Holly Black, and it's VERY good. It's about a teenager, Kaye, who finds out that she is really a changeling, or a faerie enchanted to look human, and her "glamour," or human disguise, is only a mask. The adventures she goes through in this book are exciting, suspenseful and unique. If you haven't read it, you definitely should. I'm making a quiz on it now.
