Filip turned back. Miral and Josie had cut the canisters free of their pallets and strapped one to the scaffold. The flashing emergency lights had dimmed, the relief vehicles passing them by in the haze and confusion. Heading, likely, for the firefight at the armory. It was where Filip would have seen the greatest threat too, if he hadn’t known better.

“Bosslet,” Andrew said, his voice thin and anxious. “Cutting close here.”

“No preoccupes,” Filip said. “Ge gut.”

One of the two guards put a hand on his shoulder. “You want me to go fix that?” she asked. Should I go save them?

Filip lifted a fist and shook it gently back and forth. No. She stiffened when she understood what he was saying, and for a moment, he thought she’d disobey. Her choice. Mutiny now was its own punishment. Josie slid the last canister into place, tightened down the straps. Aaman and his people fit the last brace in position.

One minute, twenty seconds.

“Bosslet!” Andrew screamed.

“I’m sorry, Andrew,” Filip said. There was a moment of stunned silence and then a stream of obscenity and invective. Filip changed frequencies. The emergency services for the military shipyards were shouting less. A woman’s voice speaking crisp, calm German was delivering commands with the almost-bored efficiency of someone well accustomed to crisis, and the voices answering her took their professionalism from hers. Filip pointed to the scaffold. Chuchu and Andrew were dead. Even if they weren’t dead, they were dead. Filip pulled himself into his position on the scaffold, fitted the straps around his waist and under his crotch, across his chest, then laid his head back against the thick padding.

Fifty-seven seconds.

“Niban,” he said.

Nothing happened.

He turned his radio back to the encrypted channel. Andrew was weeping now. Wailing.

“Niban! Andale!” Filip shouted.

The evac scaffold bucked under him, and he suddenly had weight. Four chemical rockets under high burn lit the ground below him, scattering the empty pallets and knocking Miral’s abandoned loading mech on its back. Acceleration pushed the blood down into Filip’s legs, and his vision narrowed. The sounds of the radio grew thinner, more distant, and his consciousness flickered, stuttered. His suit clamped down on his thighs like being squeezed by a giant, forcing the blood back up out of them. His mind returned a bit.

Below, the crater was an oblong blister of dust on the face of the moon. Lights moved in it. The towers at the crater’s edge had gone dark, but flickered now as the systems tried to reboot. The shipyards of Callisto reeled like a drunkard, or a person struck in the head.

The countdown timer slid to two seconds, then one.

At zero, the second strike came. Filip didn’t see the rock hit. As with the tungsten slugs, it was going much too fast for mere human sight, but he saw the dust cloud jump like someone had surprised it, and then the vast shock wave, blooming out so powerfully that even in the barely-extant atmosphere it was visible.
