In a future Earth city starved of power and hope, Ryd Randl drifts through the freezing streets of Dynamopolis, a broken former helio operator watching his world shrink under Martian dependence. When the long-awaited power cylinder arrives, it promises renewal—but to Ryd, it feels like one more humiliation. Then a stranger named Mury finds him in a bar and offers money, purpose, and a path out of ruin. What follows is a plunge into conspiracy and rebellion. Mury believes the cylinder is not salvation but proof that Earth has become a labor colony for Mars, and he recruits Ryd for a desperate sabotage mission at Pi Mesa spaceport. Under cover of night, the pair kill a guard, seize his uniform, and force their way aboard the towship Shahrazad. But the hijacking is only the beginning. Trapped in the airlock, then thrust into the cold machinery of space travel, Ryd is swept deeper into Mury's ruthless plan as the stolen ship races past the Moon, hunted by a warship and driven toward a confrontation that could decide Earth's fate.
