“I don’t care about your rules. I don’t care if you burn this entire city to the ground tonight. If they leave a single bruise on her skin, I will peel the flesh from your skull while you are still breathing.” They call him the Boogeyman - a monster that spares no one. Jungkook is the Syndicate’s most lethal weapon—a hitman who never misses, never questions an order, and never leaves a survivor. Until her. She was supposed to be just another target, a pawn in a deadly mafia game. But when he looked at the terrified girl during his mission, everything changed. Instead of ending her life, he took her. He locked her in a glass cage in the sky, branded her as his own, and swore to protect her. For the first time in his life, the monster had a weakness. But in the Syndicate, weaknesses get you killed. His boss, Silas, wants his perfect killer back on a leash. To teach Jungkook a lesson, Silas drags the girl into the dark and murders the only other person Jungkook ever loved: his brother, Jimin. Silas thinks the grief will break him. He thinks the Hitman will finally surrender and obey. He is dead wrong. Silas didn't leash a dog. He unchained a demon. Now, Jungkook is tearing the city apart. He has dropped his guns, left his empire behind, and is walking straight into a bloodbath with his bare hands to get her back. Expect: A ruthless anti-hero, a terrifyingly possessive romance, high-stakes mafia warfare, and a girl who finds out that the safest place in the world is in the arms of a killer. Will he reach her before the Syndicate breaks her mind? Can a man who only knows how to kill ever learn how to truly love? Or will the ashes of his revenge bury them both?
