I did really did enjoy this books, having read quite a few adult books about the subject of eating disorders I didn't expect much from a YA book, but the book is well researched and not too in depth and graphic, which is ideal for younger readers.
I didn't like the formatting of the book, all the crossing out of text in the middle of sentences. For me it got a bit too confusing at times, but it didn't put me off the overall book.
