Really enjoyed this book. A light read, very very thin, you could probably finish it in less than a few hours. It's a gripping thriller and I was really hooked onto it within the first chapter already. It doesn't waste anything, doesn't shy away from certain topics, and even manages to portray Zinny's relationship with his family very well as well.
Also, about time we had a teenager with no friends who *doesn't* keep going on about how he has no friends. More like he as lot more problems than that: such as being threatened, blackmailed, bullied, no income coming in, no food, can't pay the rent, mother in hospital, and so on. Like school is the least of his problems.
I also found the villain of the story genuinely threatening too (more so than the generic thugs of another similar book I read last week). I wouldn't give it a high score though because it is quite simple at its core, but it is still done very well.
