I love Cat Clarke's books, really. I think I just expected too much from this book. Also I didn't like the characters at all, except Kai, even though he's dead. I mean, this guy is perfect.
I didn't like Jem at all, because all she wanted really was to blame certain people for what happened. It wasn't even really seeking the truth, it was just to blame someone, because she needed it, she didn't even think of other possibilities. To her, it must have been the popular kids, not someone else. Moreover, she wanted to kill herself, so the end wasn't really surprising.
