The amber maintenance lights of cargo-transfer bay three cast long, stretching shadows across the deck, painting the frost-rimed bulkheads in the color of old honey. It was the ragged edge of the night-cycle, that quiet, hollow hour when the rest of the Aurora Space Station was asleep and the ambient hum of the life-support trunks sounded like a massive, sleeping beast taking slow breaths.
Maria Castaneda wiped a streak of grease from her forehead with the back of her wrist, leaving a smudge across her brow, and leaned her weight against the heavy mag-pallet. The hydraulic lock clicked, a heavy, satisfying sound that signaled the final crate of hydroponic seedstock was secured to the decking.
“There,” Maria said, blowing a stray strand of dark hair out of her eyes. “That is the last of the winter-wheat strain. If this batch does not take, I am going to personally write a strongly worded letter to the soil microbes.”
Cassian Holt stood a few paces away, checking a datapad. The low light caught the silver in his eyes and the faint dusting of gray at his temples. He moved with a quiet, deliberate grace that always made Maria’s pulse do a strange little stutter-step. He tapped the screen of his pad, his expression unreadable, though Maria knew him well enough to spot the tiny crinkle of amusement at the corner of his mouth.
“The microbes do not read your letters, Maria,” Cassian said, his voice a low, dry rumble that vibrated pleasantly in the cold air of the bay. “And they certainly do not care about your threats.”
“They care,” Maria insisted, slapping the side of the mag-pallet affectionately. She had named this particular cargo lift ‘Bessie’ three weeks ago, and so far, Bessie had not jammed once. “It is all about establishing dominance early in the crop cycle.”
Cassian shook his head in mock exasperation, lowering the pad. “Just make sure the nutrient ratios are locked. We are already running twenty minutes over shift, and the temperature in here is dropping.”
He was right. The chill of the deep-space vacuum beyond the exterior doors was seeping through the heavy shielding, biting through the thin fabric of Maria’s service technician jumpsuit. She shivered, though she would never admit to being cold in front of him. Cassian was her senior mentor, the man who had taught her how to coax life out of recycled water and synthetic light, and she still felt the burning need to prove her competence to him every single shift.
“Nutrient ratios are locked, sealed, and blessed by the station spirits,” Maria said. She reached into her pocket, retrieved a crinkled, iridescent wrapper from a synthetic strawberry candy, and carefully wedged it behind the mesh grille of the nearest ventilation duct.
Cassian watched her, his thumb idly stroking the inside of his left wrist—a gesture he made whenever he was tired, tracing the thick, puckered scars that vanished up his forearms beneath his sleeves. Maria forced her eyes away from the movement, a familiar, heavy knot of guilt tightening in her stomach.
“A candy wrapper, Maria?” he asked softly.
“It is an offering,” she replied, dusting off her hands with exaggerated briskness. “For the gravity compensators. They have been working hard. And Rian Kade told me the shipment came from a drifter vessel that had a haunted airlock, so I am taking no chances.”
“Rian makes up half his stories to entertain himself,” Cassian pointed out, stepping closer to inspect the lock on the mag-pallet. He smelled of ozone, clean sweat, and the sharp, green scent of the hydro-bays. “And the gravity compensators do not eat candy.”
“It is the thought that counts.” Maria turned toward the primary console, her boots ringing softly on the metal grating. “Besides, Rian is safely asleep in his bunk, and we are out here wrangling seeds at two in the morning. I think we deserve a little superstitious leeway.”
She reached for her orange maintenance tablet, ready to hit the final sequence that would clock them off and release the bay doors so they could finally go get a hot meal. The fatigue was settling into her bones, a dull ache in her lower back from lifting and guiding the heavy pallets.
“All green on my end,” Cassian said, sliding his stylus into the neat, color-coded row in his breast pocket. He always kept them perfectly organized. “Let us shut it down.”
Maria tapped the screen. The system chimed a pleasant confirmation. But just as her finger moved to the final ‘END SHIFT’ command, the display flickered. The comforting green text dissolved into static, and a single amber warning icon pulsed in the upper right corner of the console.
“Wait,” Maria muttered, leaning closer to the screen. “I am getting a fault reading on the manifest sync.”
Cassian stepped up behind her. He was close enough that the warmth radiating from his chest ghosted against her back. The physical proximity sent a jolt of electricity down her spine, temporarily overriding her exhaustion.
“A fault?” Cassian murmured, his tone shifting instantly from dry banter to quiet professional focus. “Which subsystem?”
“It is not saying. Just a generic sync error.” Maria frowned, tapping the screen a few more times. “Probably just a latency issue with the central core. I will just force the override and—”
“Do not force it,” Cassian warned gently, reaching out as if to cover her hand, though he stopped an inch short. “If the manifest is not clean, the system might reject the seedstock entirely during the transfer to hydro. Let it cycle.”
Maria sighed, dropping her hand. “Fine. Cycling.”
She waited, watching the little amber icon spin. The silence in the bay stretched, thick and heavy. Maria tried to focus on the screen, but her awareness was entirely anchored on the man standing just over her shoulder. She could hear his steady breathing, feel the solid, unyielding presence of him. It was maddening how much space he took up in her head, how every casual word or dry smile from him felt like a puzzle she needed to solve.
The spinning icon froze.
Then, without warning, the amber light vanished.
In its place, the bay was abruptly flooded with a harsh, pulsing red glare.
A klaxon shrieked, a deafening, rhythmic wail that bounced off the steel walls and rattled Maria’s teeth. The heavy exterior blast doors at the far end of the bay groaned, massive pneumatic locks slamming shut with a finality that vibrated through the floorboards.
The orange maintenance tablet in Maria’s hand buzzed violently, slipping from her grip. It clattered onto the metal top of Bessie the crate, spinning once before coming to a halt.
Maria jumped back, her heart hammering against her ribs. “What the hell?”
Cassian was already moving. He swept past her, his eyes scanning the red-drenched bulkheads. “Dock-hold. The system just triggered a full isolation lockdown.”
“For a manifest glitch?” Maria scrambled forward, snatching up the tablet. The screen was completely locked out, displaying a single, glaring prompt in stark black letters: ‘REQUIRES DUAL BIOMETRIC SIGN-OFF’.
“It is not just a glitch,” Cassian said grimly, staring at the sealed doors. “The station AI thinks there is a bio-hazard or a critical mismatch in the cargo we just brought in. It sealed the bay to prevent contamination.”
Maria stared at the tablet. “It wants both our thumbprints to clear it. But we cannot clear it if we do not know what the fault is.”
“Comms,” Cassian ordered, already tapping his earpiece. “Get Operations.”
Maria tapped her own headset, switching to the command channel. “Operations, this is Cargo Bay Three. We just got slammed with a dock-hold. What is going on up there?”
There was a brief crackle of static, followed by the cool, unflappable voice of Tamsin Wei. “I see it, Castaneda. Bay three is locked down tight. The system is throwing a massive fit over the winter-wheat manifest. It flagged an unregistered biological anomaly.”
“An anomaly?” Maria echoed, looking at the towering stacks of pallets. “It is dirt and seeds, Tamsin. It is supposed to be biological.”
“Tell that to the automated safeties,” Tamsin replied dryly. “I am looking at the logs now. It is tied directly to the biometric signatures that logged the cargo in. That means you and Holt.”
Cassian stepped up beside Maria, his expression taut. “Tamsin, can you force an override from Ops? We have been on shift for fourteen hours.”
Tamsin paused for exactly one beat. “Negative, Cassian. You know the protocol. A dock-hold on agricultural imports requires a localized, dual sign-off. If I override it from up here, the system automatically purges the cargo into the incinerator chutes to protect the station’s ecosystem.”
Maria blanched. “You cannot purge this shipment! The entire next crop cycle depends on this wheat strain. If we lose it, the station is on half-rations by month six.”
“Then I suggest you two find the anomaly and clear the fault,” Tamsin said, the faint sound of her spinning her stylus audible over the feed. “I cannot open those doors until you do. No one else on shift has the clearance to touch hydro cargo in a lockdown.”
“Just remote in and point us to the specific crate,” Maria pleaded, her anxiety spiking. The red lights were making her dizzy, the pulsing rhythm feeding a sudden, sharp claustrophobia. She hated being locked in. She hated the feeling of being trapped, especially when it was her own actions—her own login—that had triggered the trap.
“I cannot,” Tamsin said calmly. “The lock is localized. You have to hunt it down yourselves through the terminal logs on that tablet. I will monitor your oxygen levels, but otherwise, you are on your own until you give the system two thumbs.”
The comms clicked off, leaving Maria and Cassian alone in the pulsing red wash of the alarm.
Maria stared at the tablet, her pulse drumming a frantic beat against her throat. “This is ridiculous. It has to be a sensor ghost. Let me just jab the sign-off and we can figure it out tomorrow.”
“No.” Cassian’s voice was hard, a flat command that left no room for argument. “We do not blind-sign a quarantine lock, Maria. If there is a real contaminant in that soil and we introduce it to the hydro-ring, it could wipe out the entire food supply.”
“I know that!” Maria snapped, the stress cracking her usual sarcastic armor. “But I also know that this automated system is notoriously paranoid. Rian said it locked down Bay Four last month because it registered a stray piece of lint as a parasitic fungus.”
“Rian is not the one who has to sign his name to the safety of two hundred people,” Cassian said softly. He looked at her, his silver eyes catching the red light. “We do this by the book. We trace the manifest logs crate by crate until we find the mismatch.”
Maria swallowed hard, her anger deflating instantly. He was right. He was always right when it came to the safety protocols. “Fine. By the book.”
Cassian nodded once, picking up the orange tablet. “I will take the port side pallets. You take starboard. We cross-reference the physical tags with the encrypted manifest.”
The cargo bay felt suddenly, impossibly small. The towering stacks of crates created a labyrinth of narrow aisles, bathed in the sinister red glow. Maria moved into the starboard stacks, scanning the bar-codes on the pallets with her wrist-scanner.
The low hum of the life-support trunks seemed louder now, a constant, oppressive vibration. Maria’s hands shook slightly as she scanned the third crate. Her mind was racing, trying to find a joke, a quip, anything to diffuse the suffocating tension. But the red light and the locked doors pressed down on her, leaving her breathless.
“Anything?” Cassian called out from a few aisles over.
“Nothing but perfect, glorious, un-anomalous dirt,” Maria called back, her voice sounding thin and reedy.
She moved deeper into the stacks. The aisles grew narrower here, the massive crates pressing in on both sides. She turned a corner and nearly collided with Cassian, who was backing out of a tight space between two pallets, holding the tablet up to catch the light.
Maria gasped, stumbling backward. Her heel caught on the edge of the floor grating, and she pitched backward.
Cassian moved with terrifying speed. He dropped the tablet—it bounced harmlessly on the deck—and lunged forward, catching her by the upper arms before she could hit the floor.
His grip was iron-strong, hauling her upright and pulling her flush against his chest. The impact knocked the breath out of her lungs. For a second, the universe shrank down to the narrow space between the crates, the frantic pulsing of the red light, and the solid, undeniable heat of his body pressed against hers.
“Careful,” Cassian breathed, his voice rough.
Maria looked up. His face was inches from hers. She could see the faint lines around his eyes, the slight stubble on his jaw, the way his pupils were dilated in the dim light. His hands were still gripping her arms, his thumbs pressing into her bare skin where the sleeves of her jumpsuit were rolled up.
She looked down at his hands. In the red wash of the alarm, the thick, jagged scars across his forearms looked stark and angry. The old, familiar guilt surged up in her throat, choking her. She had caused those scars. Two years ago, she had overridden a safety protocol to save a harvest, and the caustic spray had burned the flesh right off his arms. He had never blamed her, had never even hinted that he knew it was her fault, but she knew.
And now, here they were again. Locked in, trapped by an automated safety system, with her own login tied to the fault.
“Cassian,” she whispered, her voice trembling.
She reached up, her fingers trembling, and lightly traced the edge of the scar on his left wrist. The skin was smooth, tight, and completely numb in places, but Cassian drew a sharp, hitching breath at her touch.
“Maria,” he warned, his voice dropping an octave, vibrating with a sudden, dark intensity.
She didn’t stop. She couldn’t. The fear and the guilt and the years of suppressed, agonizing desire all tangled together in her chest, demanding a release. She slid her hand higher, her fingertips trailing up the scarred skin of his forearm, slipping under the heavy fabric of his uniform sleeve. His skin was burning hot beneath her touch.
Cassian’s eyes darkened. He didn’t step back. Instead, his grip on her arms tightened, pulling her a fraction of an inch closer, until their hips brushed. The contact sent a jolt of pure, liquid heat straight to her core.
“We have to find the fault,” he murmured, though he made no move to pick up the tablet. His gaze dropped to her mouth.
“I know,” she breathed. She leaned in, entirely on instinct, her lips parting. The air between them was thick, charged with a heavy, desperate gravity. She could feel the erratic pounding of his heart against her own chest.
He leaned down, his face angling over hers, the space between their lips vanishing. Maria closed her eyes, her body arching upward, aching for the crush of his mouth.
A sharp, shrill beep from the deck shattered the moment.
The orange tablet, lying abandoned on the grating, flashed a bright, insistent white light.
Cassian flinched backward as if he had been burned, releasing her arms and taking a massive step back. He dragged a hand through his hair, his chest heaving, his eyes wide and shocked.
Maria staggered back against the crate, her whole body trembling, her lips still tingling with the ghost of a kiss that hadn’t quite happened. The cold air rushed into the space between them, freezing the sweat on her skin.
Cassian bent down and snatched up the tablet. He didn’t look at her. “It... it isolated the fault,” he said, his voice clipped, stripped of all emotion. “Crate forty-two. We need to crack it open.”
Maria stared at him, her heart breaking a little at the sudden, impenetrable wall he had thrown up between them. She looked at his scarred hands, gripping the orange tablet, and then at the sealed blast doors bathed in unforgiving red light.
With the bay sealed and the orange tablet insisting on dual biometric sign-off for a fault she might have caused, Maria looked over at Cassian’s scarred hands and realized there was no way out of this night—or of facing what lay between them—except through him.
