I attempted to read this book in small chunks, but it demanded that I sit down and read it all at once. Yes, it's dystopian, but it's also sci-fi-futuristic-militaristic. It won't be out for another couple of months (huzzah for friends with ARCs!), so when November rolls around, I highly recommend getting your hands on a copy. 
 (view spoiler)[(My one, tiny complaint is that I wish there wasn't so much romance. I know, I can't believe I'm saying that either. June and Day obviously make a fabulous couple, but it was very sudden. I would have saved it up and channeled the tension into the sequels.) (hide spoiler)]
