So good. SO GOOD. I loved this book. There's a reason I've shelved this on (among others) my dystopia shelf, my philosophy/religion shelf, and my sci-fi/fantasy shelf. It was all over the place - in the best way possible. 
 This reminded me a lot of Jostein Gaarder's Sophie's World, also one of my all-time favorites. Using philosophy and Socratic dialogue to examine all kinds of ideas - justice, morality, education, privilege, equality, slavery, the role of technology in a society, divinity and religion, censorship - it doesn't get any better than this. 
 I read this book in a day and came on here fully prepared to rave about it and yet still dock it a star for the abrupt ending. However, thirty seconds of research tells me that there is a sequel forthcoming, and so I immediately undocked the star. I can live with a cliffhanger ending if I know there's more to come!
