Level 999: The Glitch King

When Earth is marked for deletion during an unscheduled System Update, Jace should have died with everyone else. Instead, the system fails to classify him. Branded an Error-Born anomaly and assigned the impossible designation of Level 999, Jace becomes the one existence the universe’s ruling protocols were never built to contain. But a forbidden level means nothing when his access is locked, his authority is restricted, and every celestial enforcer in the system wants him erased before he can fully awaken. As cities fall, sectors open, and reality reveals its artificial design, Jace must unlock the broken permissions buried inside his Glitch Protocol. Every battle increases his access. Every breach brings him closer to the truth. And every enemy he destroys proves the same terrifying fact: the system did not choose him. It failed to stop him. — Description from novelcodex.org
