After reading the opinions of other readers here, I wondered if we had all read the same book. I suspect that those who find this book a disappointment came to it hoping to read a work more in line with previous books by either of these two well-respected science fiction authors. Finding something different, they left unsatisfied. If one approaches this book with an open mind, I think they will be pleasantly suprised. The two authors paint a convincing, detailed alternative history that weaves several narratives into a cohesive whole that falters only slightly at the end. The characters are for the most part three-dimensional, and fit well within the world Gibson and Sterling have created. The atmosphere is dark and brooding, and the benifits and costs of an England dominated by steam-driven computers are well represented. The poltical climate and "world of the difference engine" are both plausible and entertaining. The only place in which the authors falter is in their attempt to move the narrative beyond entertainment into the philosophical and metaphysical. Then ending is somewhat reminiscent of the finale of Nueromancer, and is written in the sterotypical clipped Gibson style, which contrasts sharply with the rest of the novel. Had Gibson and Sterling left their work in the more mundane realm of (alternative) historical adventure, they would have had an unqualified success. Depsite that shortcoming, I recommend this book wholeheartedly. It is unlike any other work by these two authors, and thus you should expect something different. It is a rousing adventure set in a plausible alternative world, similar in tone and style to Frost's excellent "List of 7," only slightly hindered by some metaphysical trappings.
