The Stone Dogs

Since the Draka conquest of Europe and most of Asia in the 1940s, the American-led Alliance and the Domination of the Draka have glared at each other across the oceans, restrained only by the threat of thermonuclear annihilation. In this Cold War there can be no compromise, no detente, no happy tearing down of walls, only ultimate enmity.
The Alliance, using its superiority in computer technologies, is preparing a master stroke of electronic warfare. The Draka, supreme in the ruthless manipulation of life's genetic code, have a secret weapon of their own. Both sides await only the right moment to strike.
From the manor-houses of the Draka aristocracy and the streets of an alternate-world New York to the farthest reaches of the Solar System, the Draka and their enemies carry on a struggle whose victor will decide the fate of humanity - to be forever free or forever slave.
