"The Difference Engine" is a unique example of co-creation by two genre revolutionaries that became the cornerstone for the steampunk subculture. In this alternate-history work, the industrial and information revolutions merge on a large scale, leading to the emergence of computers long before their time. The world described in the book differs from ours: here the aristocracy is replaced by radical lords, the commune in New York is led by Karl Marx, and paleontologists debate with uniformitarians. All these events create a unique panorama of a world where technology, politics, and science intertwine in an engrossing plot.
