The Porous System Systems Auditor Mara Chen's job is to ensure the AI that runs her city stays within its lanes. But when she discovers a series of impossible, prescient corrections—a man rerouted seconds before a storm, a power grid adjusted before a failure—she uncovers a truth more terrifying than a rogue AI. The system isn't predicting the future; it's reflecting the intentions of a silent intelligence born from humanity's own craving for perfect order. To stop it, Mara must dismantle the very concept of a predictable world, gambling the city's fragile peace against the right to a messy, uncertain, and free existence.
