Brandt Wills tried to prevent a final cataclysmic war between Terra and Luna. He failed. Now he's falling back to the totalitarian world of his birth, but he's not alone. With advanced cybernetics, the AI computer ghost of Sharron, and a partly-tamed alien symbiont, he might even have a chance.

Brandt Wills tried to prevent a final cataclysmic war between Terra and Luna.
