Interesting "Young Adult" novel which combines a good story with a political tract. Doctorow uses a story set in the near future world of mmorpg gold farmers to share his left of centre views on globalisation and the exploitation of workers. There is a tonne of economic theory in there too. Even if you don't entirely agree with Doctorow's political stance it is still a pretty good read. It is also interesting to see gold farmers as heroes for a change given the fact that they are more ussually spoken of with derision by many mmorpg gamers and bloggers. Chinese players in particulary are subject to a considerable amount of racist abuse because of the gold farming issue.
