Amazon.com ReviewA collaborative novel from the premier cyberpunk authors, William Gibson and Bruce Sterling. Part detective story, part historical thriller,The Difference Enginetakes us not forward but back, to an imagined 1885: the Industrial Revolution is in full and inexorable swing, powered by steam-driven, cybernetic engines. Charles Babbage perfects his Analytical Engine, and the computer age arrives a century ahead of its time.From Publishers WeeklyIn a surprising departure from the traditional view of cyberpunk's bleak future, Gibson ( Mona Lisa Overdrive ) and Sterling ( Islands in the Net ) render with elan and colorful detail a scientifically advanced London, circa 1855, where computers ("Engines") have been developed. Fierce summer heat and pollution have driven out the ruling class, and ensuing anarchy allows the subversive, technology-hating Luddites to surface and battle the intellectual elite. Much of the problem centers on a set of perforated cards, once in the possession of an executed Luddite leader's daughter, later in the hands of "Queen of Engines" Ada Byron (daughter of prime minister Lord Byron), finally given to Edward Mallory, a scientist. Mallory, who knows the cards are a gambling device that can be read with a specialized Engine, is soon threatened and libeled by the Luddites, and he and his associates confront the scoundrels in a violent showdown. A sometimes listless pace and limp conclusions that defy the plot's complexity flaw an otherwise visionary, handsomely written, unsentimental tale that convincingly revises the 19th-century Western world. 75,000 first printing; $75,000 ad/promo.Copyright 1991 Reed Business Information, Inc.
