The Unseen Night Guard

In an American city split into shadow districts by a port, subway tunnels, neon corridors, and corporate wealth, night-shift rail mechanic Ethan Carter unexpectedly gains the ability to hear the "echo memories" trapped inside steel, pipes, and track structures. He only wants to survive, pay off his mother's medical debt, and keep his head down, but after a disaster that the media twists into a crime, the whole city brands him a villain. As the underground criminal network, a private security empire, and a mayoral-election conspiracy surface, he is forced to fight back in the dark as an unnamed guardian, turning the city itself into a weapon, clearing his name, saving the city, and finally exposing the truth in a live broadcast watched by everyone.
