Naughts and Crosses is the amazing book by Malorie Blackman. Basically, it's about two kids in love living in a reverse society -- "blacks" are the majority and "whites" are the minority. The girl is black and the guy is white. It's crazy because the whole concept isn't even fully realized until you're a good number of chapters into the book. I just thought the whole flipside story of our reality was mind boggling and thought provoking, inspiring me to use the book title for my user name.
There's your unnecessary clarification.
