Zara was a Fixer. Her job was to hunt down anomalies in the city’s nervous system: glitching ad-boards, mismatched facial recognition tags, the occasional love letter flagged as a terror threat. She worked from a cramped pod in the underbelly of Sector 7, surrounded by humming servers and the ghost-light of a thousand old conversations.

For three days, she traced shadows. She followed the empty spaces between data packets, the gaps where a smile should have triggered an ad for dental implants, the silence where a laugh should have spawned a meme. She found Lina in the things the system didn't record: a chair pulled out from a table with no occupant logged, a book checked out from a dead library with no borrower ID, a song hummed on a street corner that no voice-recognition algorithm could match to a profile.
