If I could give it half a star or less I would. 
 I have never hated a book so quickly before. It was horrendous from start to finish. None of the characters have any redeeming qualities and when an author tries to make drug taking seem like a cool, sexy, desirable quality in a person then that is where I draw the line. I'm not a prude when it comes to drugs by any means but the whole 'yeah I take drugs, you're not gonna make me stop' thing is just dumb. I know not everything is what it seems with it but still up until the "big twist" it's just ridiculous. The twist itself is also hilariously bad. If i'd known what this was going in, i'd have never read it, it's one of my plot pet hates, such an over done concept and every other time i've read it done before, it's been done a million times better. Read Cross my Heart by Katie Klein if that's what you're into. 
 The writing is far too formal and doesn't fit with the age group of the characters. In fact I don't think I'd enjoy this style of writing no matter what ages they were. It just didn't agree with me and irked me for the entire duration. 
 The sheer volume of grammatical errors and the poor sentence structure was mind-blowing. This is just one of those books where I will never understand the high Goodreads rating.
