Prologue: Filip
The twin shipyards of Callisto stood side by side on the hemisphere of the moon that faced permanently away from Jupiter. The sun was only the brightest star in the endless night, the wide smear of the Milky Way brighter by far. All along the ridges of the craters, harsh white work lights glared down onto buildings, loaders, scaffolds. The ribs of half-built ships arced up over the regolith of stone dust and ice. Two shipyards, one civilian and one military, one Earth-based and one owned by Mars. Both protected by the same anti-meteor rail-gun defenses, both dedicated to building and repairing the vessels that would take humanity out to the new worlds beyond the rings when and if the fight on Ilus got worked out.
Both in a lot more trouble than they guessed.
Filip slid forward, the rest of his team close behind him. The suit LEDs had been gouged out, the ceramic plating scoured until nothing was smooth enough to cast a reflection. Even the heads-up display was dimmed almost to the point of invisibility. The voices in Filip’s ears – ship traffic, security feeds, civilian chatter – were picked up on passive. He listened while transmitting nothing in return. The targeting laser strapped to his back was powered down. He and his team were shadows among shadows. The faint countdown timer in the left of his visual field passed the fifteen-minute mark. Filip patted air barely thicker than vacuum with an open palm, the Belters’ physical idiom to move forward slowly. Around him, his team followed.
High in the void above them, too distant to see, the Martian naval vessels guarding the shipyard spoke in clipped, professional tones. As thinly as their fleet had been stretched, they had only two ships in orbit. Probably only two. It was possible that there were others hidden in the black, hugging their own waste heat and shielded from radar. Possible but unlikely. And life, as Filip’s father said, was risky work.
Fourteen minutes, thirty seconds. Two secondary timers appeared beside it, one with a forty-five second counter, the other with two minutes.
“Transport ship Frank Aiken, you are cleared to approach.”
“Message received, Carson Lei,” Cyn’s familiar growl came. Filip could hear the old Belter’s smile in the words. “Coyos sabe best ai sus bebe come we low?”
Somewhere up there, the Frank Aiken was painting the Martian ships with innocuous ranging lasers set at the same frequency as the one strapped to Filip’s own back. When the Martian comm officer spoke, there was nothing in his voice that showed fear.
“Don’t copy you, Frank Aiken. Please repeat.”
“Sorry, sorry.” Cyn laughed. “You fine upstanding gentlefolk know any good bars a poor Belter crew could get a drink once we get to the surface?”
“Can’t help you, Frank Aiken,” the Martian said. “Maintain course.”
“Sabez sa. Solid as a stone, straight as a bullet, us.”
Filip’s crew topped the crater ridge, looking down at the no-man’s-land of the Martian military yard; it was just as he had expected it to be. He picked out the warehouses and supply depots. He pulled off the targeting laser, set the base into the dirty ice, and powered it up. The others, spread along the line wide enough that none of the guards would be out of all their sight lines, did the same. The lasers were old, the tracking platforms strapped to them salvaged from a dozen different sources. Before the tiny red LED on its base turned green, the first of his two secondary timers reached zero.
The security alert tritone sounded on the civilian channel, followed by a woman’s anxious voice.
“We’ve got a runaway loading mech on the field. It’s… ah, shit. It’s heading for the meteor array.”
The panic and alarm cascaded in his ears as Filip moved his team along the rim of the crater. Thin puffs of dust rose around them and didn’t fall, widening instead like a mist. The loader mech, failing to respond to overrides, trundled across the no-man’s-land and into the wide eyes of the meteor defense cannons, blinding them, if only for a few minutes. Four Martian marines emerged from their bunker, as protocol demanded. Their powered armor let them slide over the surface like they were skating on ice. Any one of them could kill his whole team and suffer nothing worse than a moment’s pity. Filip hated them all and each one individually on principle. The repair crews were already scrambling for the damaged array. The whole thing would be back in order within the hour.
Twelve minutes, forty-five seconds.
Filip paused, looking back at his team. Ten volunteer soldiers, the best the Belt had to offer. Apart from himself, none of them knew why the mission to raid the Martian supply depot was important or what it was leading to. All of them ready to die if he told them to, because of who he was. Because of who his father was. Filip felt it in his belly and in his throat. Not fear, pride. It was pride.
Twelve minutes, thirty-five seconds. Thirty-four. Thirty-three. The lasers they’d placed came to life, painting the four marines, the bunker with the backup team, the perimeter fences, the workshops, and the barracks. The Martians turned, their armor so sensitive that even the gentle caress of invisible beams of light was noticed. As they moved they lifted their weapons. Filip saw one recognize the team, gun shifting away from the lasers and toward them. Toward him.
He caught his breath.
Eighteen days before, a ship – Filip didn’t even know which one – out in the Jovian system somewhere had made a hard burn, topping out at ten, maybe fifteen gs. At the nanosecond specified by the computers, the ship had released a few dozen lengths of tungsten with four disposable, short-burn rockets at the center of mass and cheap single-frequency sensors tied to them. They were barely complicated enough to be called machines. Six-year-old children built things more sophisticated every day, but accelerated as they were to one hundred and fifty kilometers per second, they didn’t need to be complex. Just shown where to go.
In the time it took for the signal to propagate from Filip’s eye, down his optic nerve, and into his visual neocortex, it was over. He was aware of the thump, of the ejecta plumes where the marines had been, of the two brief new stars that had been warships overhead, only after the enemy was dead. He changed his suit radio to active.
“Ichiban,” he said, proud that his voice was so calm.
Together, they bounced down the crater’s side, shuffling their feet. The Martian shipyards were like something from a dream, plumes of flame rising from the shattered workshops as the stored volatile gasses vented as fire. Soft snow billowed from the barracks as the released atmosphere sprayed out and froze. The marines were gone, their bodies ripped apart and scattered. A cloud of dust and ice filled the crater, only the guidance of his HUD showing him where the targets were.
Ten minutes, thirteen seconds.
Filip’s team divided. Three went to the middle of the open space, finding a place large enough to begin unfolding the thin black carbon structure of the evacuation scaffold. Two others unstrapped recoilless machine pistols, ready to shoot anyone who emerged from the rubble. Two more ran toward the armory, and three came with him, to the supply sheds. The building loomed up from the dust, stark and forbidding. The access doors were shut. A loading mech lay toppled on its side, the driver dead or dying. His tech specialist went to the door controls, prying the housing open with a powered cutting bar.
Nine minutes, seven seconds.
“Josie,” Filip said.
“Trabajan, sa sa?” Josie replied curtly.
“I know you’re working,” Filip said. “If you can’t open it —”
The great access doors shifted, shuddered, and rose. Josie turned back and flicked the suit’s helmet lights on so that Filip could see the expression on his craggy face. They went into the warehouse. Towers of curved ceramic and steel made great piles, denser than mountains. Hair-thin wire hundreds of kilometers long stood on plastic spools taller than Filip. Massive printers waited, ready to fashion the plates that would fit together over the emptiness, define a volume and make it a bubble of air and water and complex organics that passed for a human environment. Emergency lights flickered, giving the wide space the eerie glow of disaster. He moved forward. He didn’t remember drawing his gun, but it was in his hand. Miral, not Josie, was strapping into a loader.
Seven minutes.
The red-and-white strobe of the first emergency vehicles flickered in the chaos of the shipyard, the light coming from everywhere and nowhere. Filip shuffled down the rows of welding rigs and metal printers. Tubs of steel and ceramic dust finer than talcum. Spiral-core mounts. Layers of Kevlar and foam strike armor piled up like the biggest bed in the solar system. In one open corner of the space, an entire Epstein drive lay disassembled like the universe’s most complex jigsaw puzzle. Filip ignored it all.
The air wasn’t thick enough to carry the sound of gunfire. His HUD brought up a fast-mover alert in the same moment that a bright patch appeared on the steel beam to his right. Filip dropped, his body seeping down in the microgravity more slowly than it would have under burn. The Martian jumped down the aisle. Not the powered armor of the guards, but a technical exoskeleton. Filip aimed for the center of mass and emptied half his clip. The rounds flared as they left the muzzle, burning their own fuel, tracing lines of fire and red-gray exhaust through the thin Callistan air. Four hit the Martian, and gouts of blood drifted down in a frozen red snowfall. The exoskeleton flipped to emergency alert status, its LEDs turning a grim amber. On some frequency, it was reporting to the yard’s emergency services that something terrible had happened. Its mindless devotion to duty was almost funny, in context.
Miral’s voice was soft in his ear. “Hoy, Filipito. Sa boîte sa palla?”
It took Filip a moment to find the man. He was in his loader, his blackened vacuum suit becoming one with the huge mech as if they’d been made for each other. Only the dim split circle symbol of the Outer Planets Alliance still just visible beneath the grime marked Miral as anything but an ill-kept Martian mech driver. The canisters he’d been talking about were still lashed to their pallets. A thousand liters each, four of them. On the curving face: High Density Resonance Coating. The energy-absorbent coating helped Martian military ships avoid detection. Stealth tech. He’d found it. A fear he hadn’t known he was carrying fell away.
“Yes,” Filip said. “That’s it.”
Four minutes, thirty-seven seconds.
The loading mech’s whirring was distant, the sound carried by the vibrations in the structure’s flooring more than the thin atmosphere. Filip and Josie moved toward the doors. The flashing lights were brighter, and had taken on a kind of directionality. Filip’s suit radio filtered through frequencies crowded with screaming voices and security alerts. The Martian military was ordering back the relief vehicles from the civilian shipyard, concerned that the first responders might be terrorists and enemies in disguise. Which was fair. Under other circumstances, they might have been. Filip’s HUD had the outlines of the buildings, the half-built evac scaffold, its best guess on the locations of the vehicles given IR and light trace data too subtle for Filip’s eyes. He felt like he was walking through a schematic drawing, everything defined by edges, all surfaces merely implied. As he shuffled onto the regolith, a deep shudder passed through the ground. A detonation, maybe. Or a building finally completing its long, slow collapse. Miral’s loading mech appeared in the open door, backlit by the warehouse lights. The canisters in its claws were anonymous and black. Filip moved toward the scaffold, switching to their encrypted channel as he shuffled.
“Status?”
“Small trouble,” Aaman said. He was with the scaffold. Filip’s mouth flooded with the metal taste of fear.
“No such thing here, coyo,” he said, fighting to sound calm. “What is it?”
“Some of the ejecta crap’s fouling the scaffold. I’ve got grit in the joints.”
