Battle Royale by Koushun Takami. Bloody good story. Since I already knew what it was about I already knew what to expect. Blood and gore, Japanese style.
For those who didn’t know, Battle Royale (Batoru Rowaiaru) is about a class of high school kids who find themselves in an island where they have to kill each other until only one of them survives. That storyline itself is pretty hard core. AND irresistible. When I got hold of the book, I was just itching to know how it all went down.
