90 Seconds

From the parapet she could see the whole valley floor without turning her head. Three cylinders stood out there in a perfect triangle, dull grey and too smooth to hold a reflection, half sunk into dry grass that had flattened outward from them in rings. They did not steam or smoke. They waited. Priya licked dust from her lips, set her pencil tip to a fresh line, and kept her eyes on the leftmost cylinder while the heat made her jeans stick to her knees and the concrete burned through the denim. Dry grit stung the corners of her eyes and made her blink, and the bright glare ached in a deep place behind her eyes until colours pulsed at the edges. When the flash came, it was white and silent, a blink of light along the seam of the cylinder, and she started counting the second it faded. She felt the hum arrive later through the soles of her shoes and the bones of her knees, a low pressure that pushed at her eardrums. She marked the time in the logbook the instant the watch hand hit its mark. "Flash to hum, fourteen seconds, same as last time," she muttered, and she wrote the number twice to keep the sweat from blurring it.

Below her, the roof hatch banged open against its stop, and Theo Park shouted up through the stairwell with his voice bouncing off concrete. He was fifteen, Korean-American and lean, with short black hair stuck to his forehead and scraped knuckles on his right hand, and a grin that showed even when he was breathing hard. He hauled a laundry bag stuffed with spare blankets up the ladder one-handed, his T-shirt dark with sweat and dust, and dropped the whole load onto the tar paper with a soft thump that sent a puff of chalk dust up from a folded paper in his back pocket. "Delivery service, no batteries required," he said, and he dragged the back of his wrist across his face and sprawled for a second in the narrow strip of shade thrown by the parapet. He pulled out the paper and spread it flat under his palm, a hand-drawn map of the school and the field, and the roads toward the solar array, with hallways marked in pencil and red X marks where the tall, jointed shapes had been seen crossing. The distant low hum vibrated faintly through the rooftop under their knees, not loud enough to hear so much as feel in the teeth, and chalk dust from the map clung to his damp fingers.

Priya slid the logbook toward him so he could see the column of fourteens marching down the page, and Theo whistled low and pressed the corner of the map flat where the wind tried to lift it. He explained the red marks in quick taps, here by the bus loop and here along the fence by Field Station C, and she added the times beside them in small neat numbers while the tar stuck lightly to their shoes. The hatch creaked again before either of them could fold the map, and Samira Cole climbed halfway out with dust on her shoes and her shoulders tight from pacing. She was seventeen, Black and tall and strong like an athlete, with cropped curly hair damp at the temples and a torn jacket tied around her waist, and she held a creased school photo in one hand as if she had been carrying it for hours. "Anybody hear anything about my brother?" she asked, her eyes moving from Priya to Theo, then out toward the cylinders before coming back. "Ginger was by the array on day one, and nobody has given me a straight answer since."

The three of them went down through the hatch and into the stairwell where the air turned cooler and smelled of floor wax and old paint, and then out into the gym that had been turned into a dorm. Cots crowded the varnished floor in crooked rows, blankets piled at the foot of each one, and the high windows had been taped over with cardboard and black trash bags so no light could leak out after dark. The smell hit all at once: unwashed blankets and boiled beans from the kitchen cart and the waxy cleaner the custodians had used for years, and the murmur of many low voices filled the stuffy, warm air as parents sat on cot edges and kids shared chargers that no longer had anything to charge. Samira strode between the rows with the school photo held out, stopping to crouch beside mothers and maintenance workers, and sophomores she knew from track, and she kept her voice level even though her hand tightened on the paper. "Has anyone seen Ginger near Field Station C since day one?" she asked, and she waited long enough at each cot for people to really look at the picture before she moved on. A man shook his head without meeting her eyes, a girl whispered that the road past the array was closed, and an older woman touched Samira's arm and promised to ask her husband who drove deliveries.

Near the double doors, Principal Rosa Mendez stood on a taped X on the floor, a clipboard pressed to her chest, lists fluttering at the edges where the tape had curled. She was an adult with her hair pulled into a tight bun, and her sleeves rolled to the elbows, and she had been counting heads and cans and bottles of water since the morning the sky folded wrong above the ridge. When the generator outside sputtered and coughed, the emergency lanterns strung along the bleachers flickered, and a ripple of talk rose from the cots, and Rosa lifted both hands with calm authority. She asked for quiet voices and no movement toward the doors, and she sent two fathers to check the fuel line while she marked something on her sheet and nodded at Coach Danielle Brooks by the far wall. The room settled back into its low hum of breathing and fabric and worry, and the taped windows rattled faintly as the wind gusted, blowing grit against the glass.

By the bleachers, where a smaller group of younger kids sat cross-legged on folded gym mats, Priya knelt, set her backpack down, and unzipped the front pocket. She told them plainly what had happened three days earlier: that the cylinders had come down without a sound, that the pressure had popped ears all over the valley like descending too fast in an aeroplane, and that the tall shapes that walked out afterwards tilted their narrow heads toward any active signal. She lifted a dead phone for them to see, pried the back off with her thumbnail, and tipped the battery into her palm where the cold metal sat dull and harmless. She held up three painted stones, red, green, and white, her silent message code for the hallways. "If it hums, buzzes, or glows, it calls them. We stay dark and still," she said, and her voice stayed calm and practical while the emergency lantern flickered and threw thin shadows across the listening faces. The kids stared at the battery and then at the stones, and the hush around them grew tense and complete as even the smallest boy stopped swinging his legs.

On a cot two rows back, Felix Foster sat with his knees pulled up and his hands deep in the pocket of his hoodie. He was a freshman, small for his age and nervous with his hood up despite the heat, and he had kept his phone hidden since his mother told him to turn everything off. The screen lit up white through the fabric as it searched again for service, a sudden square of glow in the dim gym, and his fingers fumbled on the smooth glass as the light split across his lap.

The tone found the quiet and split it. It was high and thin, a mosquito whine rising from the square of white light in Felix Foster's lap, and it kept rising until it filled the gym and made the cots seem to vibrate with it. Every head turned. A mother stopped mid-sentence with her mouth open. A toddler dropped a crayon, and it rolled without a sound anyone could hear over that needle of sound.

Felix stared at his own hands as if they belonged to someone else. The phone screen showed one bar blinking in and out, then the words searching, searching, and the buzz sawed again through the warm air. Harsh white lit the underside of his chin and his wide eyes and the scared faces of the two kids on the next cot, who leaned away from the glow.

"I just wanted to call my mom; I thought maybe it would connect for a second," Felix blurted, his voice cracking high and fast. "She said to keep it off, but I thought maybe up on the bleachers it would work."

Priya was already moving. She shoved her logbook into her backpack strap and threw herself across the gap between the bleachers and the cots, her sneakers catching on a folded blanket and her knee banging hard against an aluminium frame. She landed half across Felix's legs and slapped the phone face down against the mattress. Heat from the screen burned her palm for an instant. The ozone tang of overheated plastic and electricity lifted sharp into her nose, stronger than boiled beans and floor wax and all the sour-sweet smell of too many bodies breathing the same air.

Her fingers found the seam on the back of the cheap phone. She had done this a dozen times that week in demonstrations, slow and calm for an audience. Now her nails tore at it. The cover popped and skittered under the cot. She dug the battery out with her thumbnail and flung both pieces apart, battery under the cot, empty shell into her backpack. The screen died mid-search. The tone cut out so abruptly the room rang with silence, and in that quiet Priya could hear hearts pounding, her own and Felix's and a dozen others thudding too loud in chests that were trying not to breathe.

Outside, something answered the silence.

A foot came down on the cracked football field. It wasn't a human step, just a deep, jointed thud that vibrated through the floor. Grit sifted down from the high gym windows where tape held the panes in their frames. Then another thud, spaced too far apart for anything with only two legs, heavy and deliberate and coming closer.

A wash of light swept the taped windows on the west wall. Red, white, red, white, slow and even, leaking around the edges of the newspaper and duct tape in long blades that crossed the rows of cots and the faces frozen above them.

Theo was on his feet before the second sweep finished. He crossed to the wall in four long strides and hit the switch for the overheads, then threw his jacket over the emergency lantern by the bleachers. The fabric swallowed the yellow flicker, leaving the smell of hot dust and sweat in the air. He grabbed Felix by the back of the hoodie and hauled him down off the cot and shoved him flat underneath it, pressing the boy's cheek almost to the concrete.

Samira moved the other way, low and fast between the rows. She gathered three younger kids from two cots with her arms spread wide, pulling them down to the floor behind a wall of duffel bags and spare blankets. She dragged a grey wool blanket over their heads and shoulders, tucking the edges under their knees so no pale skin showed. She pressed a finger to her lips and then pointed hard at the floor, holding the point until the oldest of the three, a girl with a braided ponytail, gave a tiny nod.

"Noses only. No moving. No talking," Theo breathed, low and firm enough to carry to the nearest rows without lifting above the hum that was now vibrating the walls. He dropped to his belly beside Felix and pulled his jacket tighter around the dead lantern until not even a thread of light escaped.

Priya dropped too. The concrete was cold through her shirt where sweat had soaked it, and dust burned in her nostrils with every careful intake. She lay prone with her backpack clutched to her chest, her wind-up watch held tight in her fist, and she did not wind it because even the small clicks would be too loud. She counted instead, one heartbeat, two, three, trying to keep the numbers steady while the tall joints outside creaked.

The creak was slow. Metal settling under weight, then lifting, then settling again. Each step sent a faint tremor through the floor, up through Priya's elbows and ribs. The scanning beam washed over the taped windows again, red and white, and this time it lingered, painting the tape lines in sharp relief. Dust motes hung in the blades of light that slipped through and glowed as they turned.

Samira was on the floor two cots over, one arm over the huddle of kids, her other hand clamped around Priya's sleeve so hard the fabric bunched and pulled. Her eyes were wide and fixed on the windows, and sweat cooled on her neck and left a dark, damp patch at the collar of her shirt. Under the blanket, the air quickly turned sour with held breath and fear.

Priya watched Samira's lips shape words without sound, shaped twice, urgent. "Ginger, stay down." It was not a name for the kids under the blanket. It was for the brother who was not there, who had vanished near the solar array three days ago, and the slip hung in the dark between them, raw and unguarded. Samira's jaw tightened as soon as the shape left her mouth, and she squeezed Priya's sleeve harder, anchoring herself.

The Walker stopped at the gym wall. The hum deepened until it lived in Priya's chest more than in her ears, a low pressure that made her want to swallow and made her ears pop. Somewhere above the roofline, something tilted, a long, slow movement with a wet, metallic sigh, and the red-white light narrowed and held on the taped glass. It was listening with heat, waiting for another buzz, another glow, another breath of electricity to answer its own.

Priya kept her face turned sideways, her mouth barely open, air moving thin through her nose. The dust made her want to sneeze. She pressed her tongue hard to the roof of her mouth and counted heartbeats against the pressure. Forty, forty-one, forty-two. The tremor in the floor held still. The scan slid up across the ceiling, slow as a hand feeling along a wall, and then it moved on.

The joints creaked again, turning. Thud. Pause. Thud. Each step fainter, angled away from the gym wall toward the asphalt and the row of parked buses by the lot. The hum thinned with distance until only the ringing quiet remained, and in that quiet the sour breath under the blankets loosened as the kids let air out all at once.

No one sat up. They waited through ten more heartbeats, twenty, until Theo eased his jacket back a fraction and peered at the dark windows. The red and white was gone. The tape hung dull and grey again. He crawled on his elbows and knees to the double doors at the side of the gym, keeping his body below the small wired glass peephole, then rose just enough to look through.

Between the buses, a shape moved, taller than the bus roofs, jointed wrong at the knee and shoulder, its head a narrow wedge that threw no light now that the scan had shut. It stepped with that same deliberate spacing, one heavy foot then the next, until the dark between two buses closed around it and the hum faded into the general night noise of wind and settling grit.

Theo lowered himself and gave two quick taps on the floor with his knuckles, the all-clear they had agreed on that morning. Breath rushed out across the gym in a wave. A baby started crying and was hushed against a shoulder. Knees ached from concrete as people shifted, and relief moved through limbs in shivers that were hard to stop.

Priya sat up slowly, her hands shaking so badly she had to press them flat against her thighs for a moment. The metallic taste of fear and ozone still coated her tongue. She pulled her logbook from her backpack strap, rewrapped it from its plastic bag where sweat had dampened the edges, and uncapped her pen. She wrote the time in small, tight numbers, then the duration with a line under it, then a new mark for the gap after the signal died.

"Forty-one seconds," she said, her voice shaking but certain in the dark. "It left when the signal died. That proves the link." She held the page toward Theo and Samira so they could see the numbers even in the dimness, proof that careful thinking could hold against the tall shapes outside.

Rosa Mendez stood near the bleachers with her clipboard pressed to her chest, her face pale in the faint light leaking from the hallway. She waited until the crying settled, then moved row by row, touching shoulders, murmuring names, pulling the room back into order with quiet hands. Near the doors she gathered Danielle Brooks and two other adults with a tilt of her head, a night meeting forming in looks and nods, voices kept too low to carry.

Theo caught Priya's eye and jerked his chin toward the side hall. Samira was already on her feet, her torn jacket retied at her waist, her school photo creased in her fist. The three slipped past the cots and into the science hallway while Rosa kept the room facing forward, Felix still curled under his cot with his empty phone shell clutched like a stone.

The hallway was dimmer and cooler, smelling of chalk dust and old cleaning fluid from the janitor's closet. The emergency lights were off here by design, and only a thin line of dusk

showed around the door at the far end. Samira paced three steps and back, her sneakers silent on the waxed tile, then stopped and punched a locker door softly with the side of her fist. The metal boomed dully and shivered cold under her knuckles.

"I am not waiting in that gym while my brother is out there," Samira said, her voice raw and low. "He was by Field Station C. Nobody has even walked that far to look. We lie on the floor and count while it walks around with him out there."

Theo glanced down the hall both ways, then knelt by the science lab closet and worked a small key from his pocket. The lock turned with a soft click, muffled by his palm. Inside, on a shelf behind stacked textbooks and a box of beakers, sat a dusty ham radio with its coiled cord and detached antenna, its dials dark. He did not turn it on. He just let them see it, then closed the door again and relocked it.

Priya laid a hand on Samira's arm, feeling the tight muscle jump beneath her palm. Beyond the walls, the distant hum rose and fell, patient, circling the school grounds and the triangle of cylinders on the valley floor. The fluorescent tube above them flickered once, buzzed, and went out, and down the hall the gym lights died with it, leaving the whole building in sudden and complete darkness.
