Replying to Battle Royale...the best book ever?

i just finished battle royale, and i have to say, it is one of the best books ever.  i actually just came from school and read it untill midnight until i finsihed.  they made a movie out of it but it was pretty crappy.  I really really recomend this book, heres what it says on the back:

Koushun TAkami's notorious high-octane thriller is based on an irresistible premise: a class of junior high school stundents is taken to a deserted island where, as part of a ruthless authoritarian program they are provided random weapons and forced to kill one another until only one survivor is left standing.  Criticized as violent exploitation when first published in Japan-where is proceeded to become a runaway bestseller- Battle Royale is a Lord of the Flies for the 21st century, a potent allegory of what it means to be young and (barely) alive in a dog eat dog world. Made into a controversial hit movie of the same name, Battle Royale is already a contemporary Japanese pulp classic, now available for the first time in the english language.
