If you haven't read this yet, what have you been doing? 
 *edit* 8/1/17. Removed from favorites shelf. When I read this book however many years ago (long before the movies came out), it was fun and different to me, and like nothing I'd read before (yes, I'm aware that Battle Royale exists. I have seen the movie, but haven't read the book). So I rated according to my enthusiasm at the time. Do I still consider it a favorite? No. But...the book will always have a special place in my heart. So I might keep the rating just as a nod to how much I loved it when I read it.
