Greed

 Once there had been a single government of Earth controlled by the western races, but the long-oppressed people of Asia finally struck back with a "cohesion projector." In an instant, the device established a solid, invisible wall of space—creating a dividing line between the superpowers, with the Asiatic Federation inside and the United Continents outside.
Both powers are tenuously perched on the brink of war until George Marquis Lorrilard comes along. A sometime lieutenant of the pitiful handful of space guards known as the United Continents Space Navy, he's used the experience to become a space exploiter. Far less driven by altruism than by the ferocious thirst and hunger of greed, Lorrilard sets a course to change forever the fate of Earth and the stars.
