Engine City

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.
