Probably the book I’ve most loved from William Gibson since his earlier work — while not giving up on the, ahem, “different” style from his later work, he seems to have blended it with the futurism of his earlier 80’s work to make something entirely new and refreshing refreshing.
Taking place in two different times completely (15-20 years in our future, and about 70 years on from that), the book features the plot device of time travel, but in a way that doesn’t break the laws of causality — each world is more like its own universe within the multiverse. The denizens from the earlier time are used as a form of labor — think Amazon’s Mechanical Turk.
While all of Gibson’s books seem to end suddenly, leaving you wishing they’d go on for just another 40-50 pages, this one is especially so — I haven’t been reading a book and wanting it *not* to end this bad in a long time. The world that Gibson has created is just so rich.
