Query: Earth-Shattering

When I first started reading this book, I realized it was just another quirky scifi book, that would end up with somebody killing somebody, and that would be the end. But as I neared the end of the book, something struck me. This COULD be OUR future...if we didn't DO something. This book completely changed my opinion about the contrast between literature and entertainment, censorship, and society in general.
