Miles Abernathy, a cynical San Francisco programmer, writes a joke line of code that accidentally becomes a lethal magical spell. Recruited by the enigmatic Sorsha, he must infiltrate the empire of tech mogul Silas Rook, who seeks to weaponize this "Killing Code" into a global reality-editing platform. Navigating a hidden world of technomancy, Miles must use his coding skills not just to hack systems, but to debug reality itself, confronting a choice between immense power and preserving the beautifully flawed, human story of the world.
