I read this book for two reasons. 
 1: A lot of people really like it. 
 2: The back flap said something roughly along the lines of: Marie Lu works for a video game company. She came up with the idea for the book while watching Les Mis and thinking about what an inspector vs criminal chase would look like in a futuristic dystopian setting. 
 I mean, awesome! Les Mis? I'm completely sold. Naturally, because I'm getting wise in my old age, I told myself the characters would be nothing like Javert and Valjean. I was right, of course. June and Day are very different. Still okay, as far as YA characters go (I'm really getting disillusioned with YA fiction characters though. They're so... not complex at all...) 
 This book was pretty predictable. Most of the major plot points you could see coming a mile away. 
 However, I will say this. Marie Lu's gaming history is clear. If this had been a video game... Augh! I would have adored it as a video game. (If you could choose which character to play for the game, and then go back and replay it from a whole new angle. The plot twists would have been much better in a game. And the Skidz fight would be awesome. It'd be the generic place in all games where you go to fight against people and A: level up and B: earn money off bets. It would be sweet!) 
 So, yeah, it was a kind of cool book, I guess. I liked Day mostly. June wasn't too annoying. Better than a lot of YA dystopians I've read recently. What more could I ask for? (An amazing one, pleaaaase?)
