The main hero, aptly titled Hiro Protagonist, stumbles into a conspiracy that involves a drug and a computer virus who are both named Snow Crash, and ancient sumerian mythology about the origin of language.
While Snow Crash has a heavy streak of satire, it still works very well as story with an excellent plot and likable (if a bit over the top) characters. The pacing is extremely fast, there aren’t any slow moments for the characters to contemplate their fate, Stephenson stacks plot event upon plot event until the whole thing seems either to tumble down or to explode. Which it does in a way, in a neat and satisfying climax. There are few novels that can fuse action, satire and inventive SFnal ideas into such a compelling mix, but Snow Crash does it extremely well.
