At first, I wasn't sure that this luminous novel should be considered YA. After all, both protagonists are not really teenagers, though one inhabits the body of a teen and the other has no memory of her mortal life and is therefore rather ageless.
But as this literally haunting love story progressed, I realized that the narrator and her beloved were dealing with issues that every teen grapples with. Both are powerless to live and love freely. Both are forced to abide by the whims of those who control them. (I'm being vague because there are a lot of surprises in this beautiful story.) And, of course, both are absolutely possessed by passion.
Read this if you are (or remember being) a sensitive, literary teen. Read this no matter who you are, because the ending is so dazzling that I want to share it with everyone.
