Wtf...just...wtf????? 
 For a YA book this was very graphic. One or two scenes even turned my stomach, and it's made of freakin' steel. o________O (view spoiler)[Jazz's dad when he was eight skinned and gutted his dog right in front of him. (hide spoiler)] 
 This was a messed up read, but also a very good one. The twist at the end I didn't see coming (view spoiler)[(but I did kinda figure out the other one, though.) (hide spoiler)] 
 I'll definitely be picking up the next book in the series, Game. 
 But I will say some parts of this did bother me. Jazz's near constant thoughts on worrying about becoming a killer, not gonna lie, they got annoying as hell. (But they were totally understandable, given the circumstances. It just felt like the characters were sometimes repeating the same conversations over and over.) 
 I wish there had been a bit more of his father, who was extremely interesting. Hell, I wish the book had been from his POV. ^^; 
 There were a couple mysteries that didn't get completely wrapped up. (One in particular drove me mad! Hopefully it'll be revealed in the next two books. it better be Lyga. -___-) 
 A solid 4 out of 5. (I wouldn't recommend this to anyone who has a weak stomach or is sensitive to rape and/or violence.)
