The Matrix is a world within the world, a global consensus-hallucination, the representation of every byte of data in cyberspace. Henry Dorsett Case had been the sharpest data-thief in the business, until vengeful former employers crippled his nervous system. But now a new and very mysterious employer recruits him for a last-chance run. The target: an unthinkably powerful artificial intelligence orbiting Earth in service of the sinister Tessier-Ashpool business clan. With a dead man riding shotgun and Molly, mirror-eyed street-samurai, to watch his back, Case embarks on an adventure that ups the ante on an entire genre of fiction.
