Working dead-end shifts to pay off his dead father's debts while his mother slowly dies from an illness he can't afford to treat. When gang enforcers corner him in an alley and beat him within an inch of his life, Theo accepts his fate. He's always been prey. This is just how his story ends. Except it doesn't. An ancient dying werewolf fleeing from hunters finds Theo bleeding out and makes a choice. With its final breath, it passes on something that hasn't been seen in five hundred years: a Royal bloodline. Theo wakes to a new reality. Enhanced strength. Supernatural senses. And a mysterious Blood Moon System that treats his life like a game with quests, levels, and abilities that grow stronger with every challenge he conquers. But this power comes with brutal rules: The Masquerade must never be broken. The Midnight Council rules with an iron fist. Born werewolves see him as an inferior mutt worthy only of death. And inside him, a beast grows stronger each day, whispering promises of violence and domination. The people who made his life hell are about to learn a hard lesson "Theodore Cross is done being prey." From underground fight clubs to pack politics, from gang warfare to supernatural hunters, Theo must navigate a hidden world where one mistake means death. He'll build his own pack from outcasts and misfits. Face enemies who've had centuries to perfect their cruelty. And somehow keep the monster inside from consuming what's left of his humanity. Because in the end, the real question isn't whether he can survive. It's what kind of monster he'll become.
