The diamond age - Neal Stephenson

Decades into our future, a brilliant nanotechnologist named John Percival Hackworth has just broken the rigorous moral code of his tribe, the powerful Neo-Victorians. He's made an illicit copy of a state-of-the-art interactive device called a young lady's illustrated primer, designed to raise a girl capable of thinking for herself. Unfortunately, for Hackworth, he loses his smuggled copy to a gang of street urchins in a mugging. One of the young thugs presents the primer to his little sister, Nell and suddenly her life - and perhaps the whole future of humanity - is about to be decoded and reprogrammed... vividly imagined, stunningly prophetic, and epic in scope, The Diamond Age is a major novel from one of the most visionary writers of our time.
