I don't know what to think of this book, which is why it gets the low rating. 
 If you take it for what it says it is, an anonymous diary of a 15 year old who falls into drugs, then it is just disturbing. I kept wishing that the inevitable outcomes wouldn't happen, that the girl would be able to stop it. If that is the case, I would rate it 3 stars. I didn't love and do not want to read it again because it's too disturbing. But it was certainly interesting and it kept me turning the pages. 
 If you don't believe it is a real diary or based off of one or several diaries of drug addicted and that it is a work of fiction, then it's just baffling. Why pretend to be a real diary when it isn't? There are plenty of horrible stories/movies/tv shows which chronicle the evils of drug use that are true out there. There are plenty of fictional accounts, but just because they are fictional doesn't take away from the power of their message. The subterfuge just doesn't make sense to me. 
 Regardless, the book made me so happy that I don't do drugs and that I do not have the type of personality that was a) curious about that stuff and b) becomes addicted easily.
