Battle Royale, Vol. 1 - Koushun Takami, Keith Giffen, Tomo Iwo, Masayuki Taguchi Ok, I'm not a massive manga fan and I bought this on a really random whim to find out what the fuss was about... and wow. Seriously, this is not a nice book by any means but it is incredible in a must-know-what-happens-next way. It's full of very graphic (well, it is manga) sex and violence, disturbing scenes of mental illness and a horrifying look at the depths of human depravity. But it also has hope against the odds, and friendship, and love.
This is a series that spans many issues and will take the reader on a journey both around the island, but also deep inside the human mind. I can understand why some people wouldn't like this book, I find it hard to apply the word 'like' to it myself without sounding like a psychopath, but it's gripping and intriguing... you are never bored. Trust me, you should read it. But make sure you come prepared with a strong stomach.
