The 20th anniversary edition of the classic steampunk novel With new commentary by the authors 1855: The Industrial Revolution is in full swing, powered by steam-driven cybernetic Engines. Charles Babbage perfects his Analytical Engine, and the computer age arrives a century ahead of its time. Three extraordinary characters race toward a rendezvous with the future: Sybil Gerard—fallen woman, politician’s tart, daughter of a Luddite agitator; Edward “Leviathan” Mallory—explorer and paleontologist; Laurence Oliphant—diplomat, mystic, and spy. Their adventure begins with the discovery of a box of punched Engine cards of unknown origin and purpose. Cards someone wants badly enough to kill for. Part detective story, part historical thriller, The Difference Engine took the science fiction community by storm when it was first published twenty years ago. This special anniversary edition features an Introduction by Cory Doctorow and a collaborative essay from the authors looking back on their creation. Provocative, compelling, intensely imagined, this novel is poised to impress a whole new generation.

Since its emergence in the seventeenth century, science fiction has been a sustained, coherent and subversive check on the promises and pitfalls of science. In their turn, invention and discovery have forced fiction writers to confront the nature and limits of reality. Different Engines explores how this fascinating symbiosis shapes what we see, do, and dream. From Johannes Kepler's Somnium to Arthur C. Clarke's 2001, science fiction has emerged as a mode of thinking, complementary to the scientific method. Science fiction's field of interest is the gap between the new worlds uncovered by experimentation and exploration, and the fantastic worlds of the imagination. Its proponents find drama in the tension between the familiar and the unfamiliar. Its readers, many of them scientists and politicians, find inspiration in the contrast between the ordinary and the extraordinary. Brake and Hook's Different Engines is a unique, provocative and compelling account of science fiction as the arbiter of progress.

In the year 2570, a sleeper will wake . . . In the mid-21st century, the Kernel, a strange object on a five-hundred-year-orbit, is detected coming from high above the plane of the solar system. Could it be an alien artefact? In the middle of climate-change crises, there is no mood for space-exploration stunts - but Reid Malenfant, elderly, once a shuttle pilot and frustrated would-be asteroid miner, decides to go take a look anyway. Nothing more is heard of him. But his ex-wife, Emma Stoney, sets up a trust fund to search for him the next time the Kernel returns . . . By 2570 Earth is transformed. A mere billion people are supported by advanced technology on a world that is almost indistinguishable from the natural, with recovered forests, oceans, ice caps. It is not an age for expansion; there are only small science bases beyond the Earth. But this is a world you would want to live in: a Star Trek without the stars. After 500 years the Kernel returns, and a descendant of Stoney, who Malenfant will call Emma II, mounts a mission to see what became of Malenfant. She finds him still alive, cryo-preserved . . . His culture-shock encounter with a conservative future is entertaining . . . But the Kernel itself turns out to be attached to a kind of wormhole, through which Malenfant and Emma II, exploring further, plummet back in time, across five billion years . . .

At the heart of every great car, there lies a great engine. The high-performance muscle car; the high-mileage family car; the high-speed race car: no matter the vintage or voltage, the torque or the task, the car with the power to move Americans—and the world—boasts an engine of remarkable ingenuity, dependability, and power. American Horsepower: 100 Years of Great Car Engines pays tribute to 25 outstanding American-made engines valued for their raw horsepower or their design simplicity, their longevity or their design innovation—or, in rare instances, all of the above. Bringing an auto enthusiast’s touch to the subject, author and photographer Mike Mueller details each engine’s conception, creators, specifications, performance records, and more. His knowledgeable, accessible text, accompanied by historical images, crisp detail shots, and studio-quality photographs, conveys with precision and unfailing interest the driving power of the great American engine.
