Prologue
Kaia
Black Star looked less like a ship than a piece of night someone had taught to move.
It hung beyond the construction yards of Caelum with most of its running lights extinguished, six hundred meters of unfinished armor and exposed superstructure turning slowly against the blue-white curve of the habitat below. Work lamps burned along its flanks in scattered constellations, illuminating open maintenance bays, incomplete radiator vanes, scaffolding, and entire sections where Federation hull plating simply ended and the darker skeleton beneath showed through. Cargo tugs crawled around it like insects around the carcass of some enormous animal, their maneuvering lights blinking green and amber as they moved containers between the carrier and the surrounding shipyard platforms.
Kaia Renn watched it through Vesper's forward cameras and decided, for perhaps the twentieth time that night, that Lucien had finally lost his mind.
"You're staring again." Niko's voice crackled through the private channel, accompanied by the faint hiss that had lived in Vesper's communications system for so long that Kaia barely noticed it anymore. Somewhere aboard their transport, he was probably bent over three diagnostic screens while pretending not to worry.
"I'm appreciating the view." Kaia flexed her fingers around the worn control grips, feeling the small vibrations of Vesper's particle system through the cockpit frame.
"You appreciate things now?" Niko asked. A diagnostic window appeared along the lower edge of her display, showing the same thruster-temperature readings she had already checked twice.
"Started yesterday." Kaia dismissed the window with her thumb and leaned farther back into the acceleration couch. "Trying to become a better person."
"I preferred you awful." Niko sent the temperature window back.
Kaia left it this time.
Vesper drifted among a cluster of abandoned construction modules nearly twelve kilometers from Black Star, powered down far enough that only essential systems remained active. The Frame's dark armor disappeared easily against the void, especially here, where the shipyard had filled the surrounding space with discarded structural trusses, inactive cargo frames, empty fuel tanks, and old machinery waiting for reclamation. Vesper had been ugly before Niko had started rebuilding it. Three years of mismatched replacement armor, battlefield repairs, and whatever parts Nexus could steal, buy, trade, or salvage had made the machine uglier still.
Kaia liked it better that way.
The left shoulder belonged to the original Tessaran test chassis. The right had been cut from an Ardent industrial conversion and reshaped by Mara until it almost matched. Federation actuator housings sat beneath the forearms. Neither rear thruster spar had been manufactured in the same decade, let alone the same factory, and the armor around Vesper's waist still carried a patch where Kaia had put a rifle round through it herself during a maintenance accident she refused to discuss.
Nothing matched.
Everything worked.
Usually.
She glanced toward the particle reserve indicator.
Ninety-four percent.
Enough.
It had to be.
"Thirty-seven minutes," Lucien said over the encrypted command channel. His voice came through cleanly, quieter than Niko's and without any trace of the static that plagued Vesper's local transmitter. "Construction shift changes at oh-three-twenty. Internal security reroutes through Sector Twelve for approximately eleven minutes."
Kaia brought up the tactical overlay. Black Star's enormous shape gained layers of translucent markings as Hana fed navigation data into her display: construction docks, sensor stations, security patrols, launch structures, maintenance corridors. Small blue icons marked civilian traffic. Red ones marked Federation security vessels.
There were too many red ones.
"There were supposed to be four patrol craft." Kaia enlarged the western edge of the shipyard and counted six.
"There were." Hana's voice joined the channel, low and tired. "Two arrived forty-three minutes ago. No announcement. No corresponding traffic authorization."
"So they're expecting us." Kaia rotated Vesper slightly with a whisper of particle output, bringing another camera angle into view.
"No indication of that." Hana paused long enough for Kaia to hear keys clicking faintly on the other end. "Could be a readiness inspection. Could be a crew transfer. Could be somebody important decided they wanted more security tonight."
"Could be they know." Kaia watched one of the patrol craft pass beneath Black Star's unfinished ventral armor.
"Could be." Lucien didn't soften the answer.
That was one of the things Kaia appreciated about him.
Most people lied when they were scared.
Lucien lied when he had a reason.
There was a difference.
A pale maintenance beacon swept across Vesper's hiding place. Kaia held still while its light passed over dead machinery and a half-collapsed cargo truss. Vesper's reactor remained throttled nearly to standby, leaving only enough particle circulation to maintain the cockpit, sensors, and emergency control surfaces.
The beacon moved on.
Kaia released the breath she had been holding and immediately frowned at herself for doing it.
"You know," Yara said over comms, her voice too cheerful for someone currently trespassing inside one of the most secure military construction projects in Federation space, "this would be considerably easier if all of you stopped talking."
"You're talking," Kaia replied. She shifted her eyes toward the tiny green indicator representing Yara's internal transmitter somewhere inside Black Star.
"Yes, but I'm charming." Yara's signal weakened as she moved deeper into the carrier. "Nobody suspects charming people."
"I suspect you constantly."
"That's because you're deeply unpleasant."
A muted sound came over the channel, followed by another voice somewhere close to Yara telling her something Kaia couldn't make out.
Yara answered whoever it was with a completely different accent.
Kaia smiled despite herself.
The little green indicator continued moving.
Thirty-five minutes.
Beyond Black Star, Caelum occupied half the horizon.
The habitat was enormous enough that distance made it difficult to comprehend. Its exterior shell curved through darkness in armored layers, covered in docking structures, transport rails, communication towers, and thousands upon thousands of lights. Civilian shuttles moved between its orbital platforms in orderly lines. Farther down, beyond the industrial shell, portions of the rotating residential sections glowed beneath artificial dawn.
Millions of people lived there.
Most of them were asleep.
Most had no idea that forty idiots were about to steal the most expensive military ship their government had built in years.
Kaia tilted her head back against the seat.
"Still time to call this off," Garrick said. Unlike Yara, he sounded completely serious.
Kaia's smile disappeared.
Nobody answered immediately.
That silence had started appearing more often as the operation approached.
It was easy to talk about stealing Black Star when Black Star existed as diagrams, construction schedules, stolen manifests, and three-dimensional projections scattered across tables. It became something else when the ship itself filled half your cockpit display.
Lucien broke the quiet.
"We call it off if Hana believes they've identified us, if Yara loses internal access, or if Mara tells me we cannot launch the ship." His voice remained level while Black Star turned slowly ahead of them. "Nothing has changed yet."
"Six patrol craft changed." Garrick's reply came with the distant metallic sound of weapons being loaded behind him.
"Yes." Lucien let that sit for a moment. "Not enough."
Kaia looked at the ship again.
They had spent years surviving on things other people threw away.
Old freighters.
Civilian Frames with armor welded onto them.
Medical supplies one expiration date away from useless.
Weapons that had already belonged to three dead governments.
Safe houses with failing seals.
Fuel rationed down to decimals.
Food stretched until Celene could make six meals out of ingredients meant for three.
Black Star could change that.
Not because it was the biggest gun in the Solar System.
Because it could carry them.
Repair them.
Feed them.
Let them disappear without begging some station governor, smuggler, corporate dockmaster, or frightened settlement to risk everything by letting Nexus stay another week.
A home that moved.
That was how Lucien had sold it to them.
Kaia had never needed much convincing.
She looked toward one of Black Star's open Frame bays, where work lights illuminated empty maintenance cradles large enough to hold an entire squadron.
Nexus barely had enough pilots to fill one corner.
"You're doing that thing again." Niko's voice returned.
"What thing?"
"The thing where you stare at something and decide it belongs to you."
Kaia rested one boot against the lower pedal and watched the unfinished carrier rotate.
"It does."
Niko sighed.
"Thirty-two minutes," Lucien said.
Kaia reached over her shoulder and pulled the helmet from its restraint.
It was old enough that the original manufacturer markings had been worn away, though a narrow red strip of cloth remained tied around one side where it couldn't interfere with the seal. The fabric had faded so badly that most people would have called it brown.
Kaia never did.
She untied it before putting the helmet on, folded the strip once, and tucked it into the small compartment beside her seat.
The compartment already held two spare connectors, an emergency injector, a photograph she almost never looked at, and a single stripped screw Niko had told her to throw away three years ago.
The helmet settled over her head.
The cockpit became quieter.
Her own breathing replaced the distant vibration of Vesper's machinery.
"Seal good?" Niko asked. A pressure indicator illuminated near the edge of her visor.
Kaia locked the neck ring and watched it turn green.
"Good."
"Heart rate's elevated."
"You're starting to sound like a medical bot."
"Heart rate remains elevated despite pilot being annoying."
"That's better."
Kaia flexed her right hand again.
Vesper answered with a minute movement of its fingers outside.
The machine's primary reactor remained throttled, but the deeper systems were beginning to wake as Niko remotely released the final safeties. Particle flow crawled through Vesper's internal lattice. Displays that had been black moments earlier came alive one after another, painting the cockpit in pale light.
Reserve.
Ninety-four.
Thermal load.
Nominal.
Right thruster spar.
Nominal enough.
Kaia narrowed her eyes.
"Niko."
"I know."
"It says eighty-eight percent synchronization."
"I can read."
"It was ninety-three when we left."
"It was ninety-three when we left because I lied to you."
Kaia stared at the number.
"Niko."
"It's fine."
"You just said you lied."
"I lied because you would've complained."
"I'm complaining now."
"Which proves my decision delayed the problem by almost four hours."
Kaia considered reaching through the comm system and strangling him somehow.
A new voice entered the channel before she could decide how.
"Mara says stop touching the synchronization limiter." Lucien sounded almost amused.
Kaia looked toward the ceiling of her cockpit as though Lucien might somehow be hiding above it.
"I haven't touched anything."
"You touched it twelve minutes ago," Mara said from somewhere aboard the transport.
Kaia glanced toward the control she had, in fact, touched twelve minutes ago.
"No idea what you're talking about."
"Kaia."
"Busy."
Mara disconnected.
Niko laughed openly now.
Kaia muted him.
Black Star continued rotating.
Thirty minutes.
A small Federation shuttle separated from the carrier's dorsal docking structure, fired a brief burst of blue-white thrust, and moved toward Caelum. Kaia automatically tracked it until the tactical system tagged it civilian-authorized.
Nothing.
Another construction tug crossed beneath the carrier.
Nothing.
A maintenance drone cluster changed formation.
Nothing.
Every ordinary movement felt suspicious once you were waiting to commit treason.
A notification appeared on Kaia's display.
INTERNAL ACCESS CONFIRMED — Y. SELN
Yara's icon turned green.
"Primary maintenance network is ours for eight minutes whenever Hana wants it." Yara had dropped the accent and sounded pleased with herself. "Secondary command access is being difficult."
"Define difficult," Lucien said.
"It knows I'm lying."
"That's because you're not charming enough."
Kaia unmuted Niko in time to hear him choking on a laugh.
Yara went silent.
"Lucien," Kaia said, adjusting the helmet seal near her jaw, "if she kills you before we start, am I in charge?"
"No."
"Why not?"
"Because you asked."
"That seems arbitrary."
"It is."
The channel filled briefly with quiet laughter.
Not much.
Enough.
Kaia looked down at her hands.
The jokes always got better when people were afraid.
Or worse.
She had never been able to tell.
Another timer appeared on the main display.
00:24:00
Twenty-four minutes.
The construction yard shifted into night-cycle operations.
External floodlights dimmed around Black Star as automated systems reduced illumination in unused sections. Several maintenance vehicles docked simultaneously. Security patrols changed vectors.
Hana began speaking more quickly.
"Patrol Three is moving early. Patrol Five has stopped near the eastern launch corridor. I'm seeing an encrypted command burst from Caelum security control."
Kaia straightened.
"Us?"
"Unknown."
"Can you break it?"
"Not before it matters."
Lucien's voice returned immediately.
"Yara?"
"Still clean." A door hissed somewhere near her microphone. "Nobody's looking for me."
"Mara?"
"Launch systems are reachable." Mara sounded as though she had been awake for three days, which was probably accurate. "Whether they'll remain reachable after we start is another question."
"Garrick?"
"Teams ready."
A pause.
Then Lucien addressed Kaia.
"Vesper?"
Kaia pushed both controls forward slightly.
Particle flow rose.
Vesper woke.
The change was subtle from inside the cockpit and enormous everywhere else.
The Frame's reactor climbed from standby. Power rushed through the distribution lattice. The dark machine loosened from its folded posture among the construction debris, fingers opening as the articulated thruster spars along its back shifted outward by a few degrees.
Kaia's displays populated with targeting information.
Six Federation patrol craft.
Three security stations.
Two active Frame hangars.
More contacts deeper inside Caelum.
Too many.
Always too many.
"Vesper's awake," Kaia said. She watched the particle reserve settle at ninety-three percent as the machine's full combat systems came online.
Niko stopped joking.
"Don't spend it all at once."
Kaia smiled inside the helmet.
"No promises."
"Kaia."
"I know."
This time she meant it.
The first time Vesper had carried her into a real fight, she had been twelve years old and stupid enough to believe surviving once meant she knew how to survive twice.
At thirteen, she stopped believing that.
At fourteen, she stopped counting how many times she had almost died.
At fifteen, Nexus had become something people outside their little network were beginning to whisper about.
Now she was sixteen.
And they were about to steal a Federation command carrier.
Kaia looked at Black Star.
Its forward armor caught the rising light from Caelum, turning one edge of the enormous vessel silver while the rest remained buried in darkness. For a moment it seemed less like a warship than a city someone had torn free and thrown into space.
Lucien's breathing came faintly across the channel.
He was somewhere aboard their little transport, surrounded by screens and stolen schedules and people who had trusted him enough to come here.
Kaia had trusted him longer than any of them.
That didn't mean she thought this was a good idea.
"Lucien," she said.
"Yeah?"
Kaia watched one of the Federation patrol craft turn beneath Black Star.
"If this goes wrong, I'm haunting you."
"I assumed."
"And I'm making it inconvenient."
"I assumed that too."
Kaia rested her thumbs against the controls.
The timer reached sixty seconds.
Across the tactical display, Nexus icons moved into position.
Yara inside Black Star.
Garrick and the boarding teams approaching from the construction spine.
Mara waiting to seize engineering.
Sera ready for the most ridiculous unauthorized launch in Federation history.
Hana watching everything.
Niko watching Vesper.
Lucien watching all of them.
Forty people.
Against a government.
Kaia's smile returned.
Fifty seconds.
Black Star's security network flickered.
Forty.
One of the exterior docking lights changed from green to red.
Thirty.
Hana spoke.
"Maintenance network compromised."
Twenty.
Yara whispered something Kaia couldn't hear.
Ten.
The construction-yard lights around Black Star went out.
Not all at once.
One section after another vanished into darkness until the enormous carrier became a black shape against Caelum's distant glow.
The Federation patrol craft immediately changed vectors.
Warnings bloomed across Kaia's display.
Seven.
Six.
Five.
Vesper's thruster spars unfolded behind her.
Four.
Particle output climbed.
Three.
Kaia pushed herself deeper into the seat.
Two.
Lucien's voice came through the darkness.
"Begin."
Vesper opened its eyes
