The city woke to rails. Not birds, not voices—rails. Beneath Mira's thin mattress the floor trembled as the 05:40 southbound slipped past Sector 7, a deep-tissue thrum she'd felt more than heard since she was small. She counted the seconds between pulses: three, four, then the eastbound answering from the spine of Ava Road. The tracks were the city's breath; everyone lived by them.
She dressed by touch: gray tunic, collar tabs for Sector 7, laces double-knotted so the monitors wouldn't ping a uniform violation. The Directors said neat clothes kept minds neat. Mira sometimes wondered if it was the other way around.
Breakfast was one mug of maize steam, sweetened with salt. Her mother stood at the window, hand on the frame, watching the inspection drones blink along the eaves. "Don't be late to Mentor Hall," she said, same as every morning. Mira nodded, same as always. They didn't talk about the father-shaped gap in the apartment or the aunt whose name was no longer said. Words were tracks too; step off them and you risked a derailment.
Outside, Ava Road moved in channels. Workers in green, students in gray, medics in white. At the crossings, the rails glowed—green pulse for go, red throb for stop, amber when the Directors pushed an announcement through the pavement speakers. *Today's gratitude: clean water, regular trams, female leadership.* Mira kept her face neutral. Gratitude was also a schedule.
She took Junction 4 instead of 3. At 3 there was a scanner; at 4 there was Eli, a boy-quick vendor with fake-wood beads. He slipped her an orange segment. "Your mum says you're too thin," he joked. She ate it walking and dropped the peel in the compost slot without breaking stride. Cameras didn't like loitering, and loitering didn't like consequences.
Mentor Hall smelled like wax and static. Director Kara stood at the front, one hand resting on the city map. The rails lit there too, little arteries feeding each sector. "We lead because we remember," Kara said. "The chaos before the tracks, the hunger before the schedules, the men who built cages and called them homes." Girls Mira's age—that is, fifteen, or as the city named it, Cycle-15—copied the sentence onto slates. Mira wrote it cleanly but felt the old itch: _who tells the story of the chaos?_
At practice drills they walked evacuation routes in silence. When Mira stopped at a red pulse, the girl behind her bumped her heel. "Keep pace," someone whispered. She did, but for a breath she looked down and thought she saw the track glow hesitate—like a skipped heartbeat—just under her shoe. She blinked and it was normal again. She didn't write that down either.
After lessons, she cut through the municipal laundry to save minutes. Humid air, soap, the clatter of bots sorting fabric by shade. Between Dryer 6 and 7 a service hatch stood propped with a brick—small rebellion or repair, Mira didn't know. She was almost past it when the hum in the pipes rose a half-note. Without meaning to, she touched the hatch latch.
The corridor lights stuttered.
She yanked her hand back. The lights steadied. A bot rolled by, chirping a maintenance code. Mira wiped her palm on her tunic, heart knocking. _Imagination_, she told herself. _Just the rails in your teeth_. She walked out, careful to match pace with a pair of medics so the cameras would see her in a crowd.
Home again, she did homework at the table while her mother filed reports. The 21:12 northbound shivered the teacup. Mira lowered her pencil and pressed two fingers to the tabletop, mimicking the pulse. This time she was sure: beneath the city rhythm, something _answered_ her.
She removed her hand. The floor hummed its ordinary song. She finished her equations. But under the neat columns of numbers she drew a small diagram only she would recognize—a rail, a break, a girl stepping sideways off the line.
