"Snow Crash", a novel by Neal Stephenson

Once a warning label for the metaverse, now basically a user manual for your daily grind. Snow Crash predicted pizza drones, avatars cooler than their owners, cyberspace sword fights, and the awkward beauty of blending the virtual with the real. Perfect companion to the CyberFinger—because if you’re going to jack into cyberspace, you might as well pay homage to the prophet who told you it would all get weird.
