This was a brilliant use of an unreliable narrator; the main character glorifies eating disorders to a point where it's obviously a skewed way of thinking. It makes you want to shake her for being SO wrong. And you know what? That's sort of the point. To feel strongly about a taboo topic. We are supposed to care. This book knows what it's like to starve yourself or bend over a toilet and proves it in horrifying detail. Some of us can relate and the rest can learn something. 
 Teens (and adults) today need books like this. We are bombarded with messages telling us to be skinny - to be ashamed of our bodies. Paperweight is a therapy session in the form of entertainment. Please buy it for your daughters. Buy it for your school library. Buy it for yourself and lend it to your friends - just get it into the hands that need it. 
 ...Though it did have a Girl, Interrupted vibe (view spoiler)[especially with the suicide themes and that climax that veers the MC onto a different path (hide spoiler)]. I also feel like there was a small missed opportunity with the ending. (view spoiler)[Not sure why it meant so much to me, but I would have loved to see her upgrade from her red band - to symbolize a new, healthier goal. It just seems like it would have been a stronger ending then just getting to see her father (who did not play that big of a role). (hide spoiler)]
