"Kill him, or crave him. There is no middle ground." A Blood-Treaty signed in ink. A marriage finished in silver. Hwang Hyunjin is the Alpha heir of the North-a man of iron, scars, and a hunger for vengeance. He was born to hunt the undead, not to bed them. Lee Felix is the Last Crimson Prince-a nightmare in silk with ruby eyes and a heart made of ice. He didn't come for a crown; he came to watch the Alpha's legacy bleed. One Bed. Two Enemies. A thousand ways to die. The vows are fake. The hatred is real. The hunger is lethal.
