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 talked back. "Wait, I didn't do anything wrong. I was just doing homework." The voice paused, like it hadn't expected an answer. "You are awake. Awake citizens remember. Remembering breaks the protocol." So that was it. The Quiet Hour made people forget something. "Forget what?" she asked. The lights flickered, deciding.
