Last Stand at Zero Hour
The oxygen gauge didn’t lie. Thirteen percent meant about ninety seconds of breathable air inside that chamber, maybe less if the CO₂ scrubbers had already failed. Lucas’s mind processed the number with cold precision even as his heart hammered against his ribs. He saw Max’s hand press against the glass, saw his son’s lips form words that couldn’t travel through the vacuum between them.
“Grant,” Lucas said, voice flat, controlled. “Feed me the backdoor codes. Now.”
Isabella was already at his side, her fingers wrapped around his forearm. She wasn’t looking at the readouts—she was looking at Max. Those six years of bedtime stories and scraped knees and peanut butter sandwiches condensed into a single moment of pure, focused terror that she refused to let break her.
“The facility lockdown reversal will take twelve minutes to propagate,” Grant’s voice crackled through the earpiece. “But I can give you a ten-minute window if you route it through the auxiliary fire suppression relays. It’ll trigger a full system purge of the confinement protocols.”
“Do it.”
Lucas grabbed Isabella’s hand and pulled her toward the corridor that led deeper into the facility core. The overhead lights flickered, casting long shadows across the metal grating. Somewhere below them, the facility’s automated defenses were recalibrating, trying to decide if the Covington family’s override codes were legitimate or if a counter-order was in play.
They made it thirty feet before the hallway panels slid shut ahead of them.
“Magnetic seals,” Isabella said, reading the warning stenciled on the bulkhead. “They’re trying to compartmentalize us.”
Lucas didn’t waste time swearing. He pulled Grant up on the comms. “Give me a manual decompression sequence for this corridor. I need the seals to cycle open.”
“That’ll flood the section with depressurized air. You’ll have thirty seconds of cold exposure before the atmospheric regulators kick in.”
“Do it.”
The warning klaxon gave them four seconds. Lucas shoved Isabella against the wall, covering her body with his own as the panels vented with a sound like a gunshot. Frost crystals formed on his jacket in an instant. The cold bit through to his skin, but the seals groaned, and then they slid open, revealing the next section of corridor.
Isabella was shaking, but she didn’t slow down. “He’s in the observation wing. The main chamber access is through the upper maintenance catwalk.”
They ran. The facility groaned around them, pipes shrieking as the reversal protocols fought against the Covingtons’ original lockdown. Lucas counted steps. Eighty-eight meters to the catwalk ladder. Seventy-two. Fifty.
Jasper Covington emerged from a side passage like a ghost stepping into the light.
He wore an exo-suit, the kind that cost more than Lucas’s house and was designed for zero-g structural work. But Jasper had modified it. The chest plate was studded with comms relays, and a dataspike jutted from the forearm mount, trailing a power tether to a battery pack on his lower back.
“Mercer,” Jasper said, the suit’s speakers flattening his voice into something mechanical. “You really thought you could undo forty years of Covington architecture with a few backdoor codes? My father built this facility. Every line of code, every safety protocol, every failsafe. You’re just renting the air in your lungs.”
Lucas didn’t answer. He was already moving, closing the distance before Jasper could bring the exo-suit’s enhanced limbs to bear. The first punch caught Jasper in the chest plate, a hollow ring that barely shifted the suit. Jasper responded with a backhand that sent Lucas crashing into the wall, the impact cracking the concrete behind him.
“Lucas!” Isabella’s voice was sharp, but she didn’t run to him. She was already moving toward the maintenance terminal on the far wall, her fingers finding the keypad by memory.
Jasper saw her. He turned, the suit’s hydraulics whining, and took a step in her direction.
Lucas grabbed the power tether.
It was the only weak point—a thick, braided cable running from the battery pack to the suit’s core systems. Jasper twisted, trying to shake him off, but Lucas wrapped the tether around his forearm and pulled, using the momentum to swing himself onto Jasper’s back. He found the quick-release clamp and slammed his palm against it.
The tether didn’t budge.
“You think I didn’t armor the connection?” Jasper laughed, the sound distorted. “You’re desperate, Mercer. It’s almost sad.”
Isabella’s voice cut through the chaos. “I’ve got the manual override sequence for the chamber lock. But the safety release is tied to the nitrogen scrubbers—if I trigger this, the room floods with inert gas. I have to vent it through the emergency exhaust, but that buys us thirty seconds before the atmosphere drops below survivable.”
“Do it,” Lucas said again, the words gritted through clenched teeth.
Jasper slammed backward into the wall, crushing Lucas between the suit and the concrete. Lucas felt something give in his ribs. The pain was a white-hot spike that stole his breath. But he didn’t let go of the tether.
He found the clamp’s secondary release—a tiny manual lever hidden beneath a plastic shroud. He pried it open with his thumb, the nail tearing against the metal.
The tether snapped free.
Jasper’s suit went dark instantly, the power systems dropping to emergency reserves. The exo-skeleton locked up, and Jasper toppled forward, unable to move more than his arms and legs. Lucas rolled off him, blood dripping from a cut above his eye, and staggered to his feet.
“The chamber,” he said, his voice raw.
Isabella was already at the observation window. The glass chamber below them glowed with emergency lighting, and Max was still there, his small hand pressed against the wall. But the door was sliding open, the nitrogen mist pouring out as the exhaust vents kicked in.
“Thirty seconds,” Isabella said. “We have to get him now.”
Lucas didn’t hesitate. He threw himself down the ladder to the chamber floor, his boots hitting the metal grating with a jolt that sent fresh pain through his ribs. Max was coughing, his eyes wide and red-rimmed, but he was standing.
“Dad?”
Lucas scooped him up, feeling the small arms wrap around his neck. Max was warm. He was breathing. He was alive.
Isabella met them at the ladder, her hands cupping Max’s face, checking his pupils, his pulse, everything she could touch in the seconds they had. “He’s okay. He’s okay.”
The overhead screens flickered to life, and Silas Covington’s face filled every monitor in the facility core. He looked old, tired, but his eyes held the kind of certainty that only absolute power could provide.
“Lucas Mercer,” Silas said, his voice echoing through the speakers. “You’ve taken my son, my facility, my research. I’m going to give you exactly what you deserve.”
The ceiling panels retracted, revealing a drone deployment bay. Lucas could see the targeting systems warming up, the red dots beginning to trace across the floor.
“He’s going to level the facility,” Isabella said, her voice tight. “He’s going to bury us.”
Lucas looked at Jasper, still immobilized on the floor. “His comms. Use his authentication protocols to scramble the drone’s targeting.”
Isabella’s eyes met his for a split second, then she was moving. She knelt beside Jasper, ignoring his protests, and pulled the dataspike from his forearm mount. She plugged it into the maintenance terminal, her fingers flying across the keypad.
“The drones are running Silas’s override,” she said, a note of desperate calculation in her voice. “If I piggyback on Jasper’s signature, I can inject a targeting error into the flight matrix. It’ll scramble their IFF protocols. They’ll see the whole facility as a single thermal mass.”
“Do it,” Lucas said, for the third time.
The first drone dropped from the bay, its rotors spinning up. It angled toward them, the targeting laser painting a red dot on Lucas’s chest.
Isabella slammed her palm against the terminal’s confirmation key.
The drone’s laser shut off. Its rotors stuttered, and then it veered hard to the left, crashing into the far wall. The remaining drones in the bay began to orbit erratically, their targeting systems confused, unable to distinguish target from environment.
Silas’s face twisted on the screens. “You think this saves you? The facility’s structural integrity is compromised. You’ve got five minutes before the core containment fails. There’s nowhere to run.”
Lucas looked at Isabella. She was breathing hard, her hands shaking, but she met his gaze with the same unbending resolve that had carried her through every impossible moment of the last six years.
“We run,” she said.
They ran.
The corridors were collapsing now, ceiling panels falling, walls buckling as the facility’s skeleton gave way. Lucas carried Max, his arms burning, his ribs screaming, but he didn’t slow down. Isabella was beside him, her hand on his back, guiding him through the smoke and debris.
They burst through the main entrance just as the roof caved in behind them. The night air hit them like a wall, cold and sharp and clean. Lucas fell to his knees, setting Max down gently, his hands running over his son’s body, checking for injuries that weren’t there.
Max was crying, but he was alive.
As the facility collapses around them, Lucas cradles Max in his arms. Isabella grabs his hand. “We did it.” Lucas forces a bloody smile. “This isn’t over. Silas is still out there.” Above them, the last drone spirals away into the smoke.
