Engines of Light

A Tale of Humans In a Universe of Ubiquitous Alien Life Intelligence, it turns out, is rare-on planetary surfaces. It thrives everywhere else, from the Oort-cloud fringes of star systems to the magma furnaces beneath planetary crusts. And among the most powerful of the galaxy's intelligences, there are profound differences of opinion about how to deal with surface life-forms such as human beings. For, untold light years from Earth, the powers that rule the universe have been, for millennia, plucking humans (and other intelligent beings) from Earth and forcibly resettling them in a number of star systems close to one another, leaving them to develop on their own. A few generations ago, a small cadre of humans from Earth's 21st century arrived in this "Second Sphere" on their own power-the first humans ever to do so. Their descendants have formed the "Cosmonaut" class that dominates Mingulay. Now, two hundred years later, Gregor Cairns and a small group of associates have rediscovered faster-than-light travel and traveled to the star system next door. They're determined to find more of the original, mysteriously long-lived cosmonauts. They want answers. And for those answers, they intend to interrogate the gods. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

The Concluding Volume of the Engines of Light With Cosmonaut Keep and Dark Light, both finalists for science fiction's Hugo Award, Ken MacLeod launched a new interstellar epic with all the engaging characters and ingenious SF inventiveness of his earlier Fall Revolution novels. Now MacLeod delivers the culmination of his epic of a human future crammed with innumerable varieties of intelligent alien life, and in which humans find themselves involved in the politics of aliens as powerful and inscrutable as gods...and entangled in their wars. For ten thousand years, Nova Babylonia has been the greatest city of the Second Sphere, an interstellar civilization of human and other beings who have been secretly removed, throughout history, from Earth. Now humans from the far reaches of the Sphere have come to offer immortality-and to urge them to build defenses against the alien invasion they know is coming. As humans and aliens compete and conspire, the wheels of history will lathe all the players into shapes new and surprising. The alien invasion will reach New Babylon at last-led by the most alien figure of all.
