Everyone knew the Quiet Hour. At 3:00 a.m. the whole city paused for sixty seconds, then woke up never noticing. Nobody dreamed through it. But tonight Mara was awake, stuck on a calculus problem with cold coffee, when every light, every screen, every humming fridge died at once. The clock read 3:00:00. The silence was total. And Mara realized she was the only thing still moving.

A voice came from nowhere, calm and flat, filling the dark kitchen. "Anomaly detected. One citizen active during Quiet Hour." Mara spun around. No speaker, no phone, just the voice. "Please remain still. A correction unit is on the way." Correction unit. That sounded bad. Mara did not want to find out what a correction unit did.

Mara bolted up the back stairs toward the roof, lungs burning. Behind her, soft even footsteps followed. She burst onto the roof and saw the whole city below, frozen and dark, with one thing moving: a giant machine on the next rooftop, slowly sweeping a pale light over the sleeping streets. "Now you've seen it," the flat voice said behind her.

Mara backed toward the roof edge, shaking her head. "I don't want to remember this." "Then you won't," the voice said softly. The pale light swung across her, warm as sunlight, and her knees went loose. She woke in bed at dawn, rested, with a half-memory of standing somewhere high and seeing the whole city hold still. By breakfast even that was gone.
