Snow Crash is science fiction at its best. The tale follows the adventures of teen skateboard courier Y.T. (Yours Truly) and pizza deliveryman Hiro Protagonist, who coincidentally, bills himself as the world's finest swordsman. Working together they discover someone is attempting to loose a deadly computer virus that might bring about the destruction of humankind as we know it.
This one has it all. Suitcase nukes, a sociopathic killer who specializes in killing with weapons of plate glass, a nuclear submarine, the Mafia, Japanese rappers, Biblical references and a virtual world (very much like Second Life and other mmorpgs) called the Metaverse.
But don't take my word for it. Check out this nifty book trailer featuring Legos and the voicework of high school English students.
