A great cyberpunk fairy tale. Neal Stephenson is the twisted love child of Frances Hodgson Burnett and William Gibson. In the future, due to advances in nano-technology it is possible to grow just about anything out of constituent atoms. Humanity's basic needs are thus pretty much cared for, but there are still privileged sections of society and not so privileged sections. Someone in one of the privileged sections decides that his children were brought up a bit too mundanely and so commissions a "Young Girl's Primer" for his granddaughter. This interactive, artificially intelligent book falls into the hands of a little girl from a not so privileged section of society and stuff happens. It's cool. Read it.
