I LOVE this book. Prose like Mafi's is unusual-especially in YA (that I've read.) I enjoyed the fact that it was actually hard to grasp at times. Mafi's writing is poetry, and before getting too used to it I made the mistake of taking some of the things she wrote too literally. I enjoyed the stream of consciousness style and even the strike-through over Juliette's thoughts. 
 I sympathized with Juliette as a main character-her insecurities, her fears, the effect of the traumas she'd experienced, all made her a more well-rounded character. One issue I did have, is the ease with which Juliette is able to begin a relationship with Adam, both emotionally and physically after spending all of her life deprived of nurture and touch. I would imagine she would have had more of an aversion to intimacy. 
 I also found Warner to be an interesting character-a foil for Juliette in a sense. Additionally, I thought this book had a lot of parallels to our real world, and followed the tradition of dystopian novels serving as a warning for what could happen in our world and what already is. This was one of the most poignant parts of it for me. 
 "Dirty money is dripping from the walls, a year's supply of food wasted on marble floors, hundreds of thousands of dollars in medical aid poured into fancy furniture and Persian rugs. I feel the artificial heat pouring in through the air vents and think of children screaming for clean water. I squint through crystal chandeliers and hear mothers begging for mercy. I see a superficial world existing in the midst of a terrorizing reality and I can't move."
