I thought that this book was pretty well written and would capture the interest of teen girls. It is realistic fiction. I would not recommend it as a book to be read as a class because I think there are other more intellectually challenging books available. That being said, I think it could be great for an independent read. It deals with the issue of cutting- and self-injurious students might be able to relate well to it. I would say that readers should be age 13 and older due to content.
