The Villain's Survival Instruction Manual

Court-martialed, disgraced, and abandoned by the world he once served, a former special operations commander awakens inside a novel he himself wrote. Reborn as the doomed son of a noble family, a villain fated to die within a month. Armed only with fractured memories and a ruthless instinct for survival, he begins drafting a private manual consisting of rules for living in a world governed by gods, bloodlines, and betrayals. As orthodox churches tighten their grip and forgotten gods stir beneath the empire’s foundations, the academy becomes a battlefield disguised as education. Secret orders hunt what they do not understand. Villains plot within villains. And every role he plays brings him closer to a fate he was never meant to survive. When a sealed god begins to descend and the price of stopping it demands blood, the rules he wrote for survival are tested one final time. — Description from novelcodex.org
