Marked by the Beast Below

I came to beg for my brother's life. He shoved a marriage contract at me instead and said I had until midnight to decide. They call Kane Voss a ruined billionaire, a recluse with a scarred face and a dangerous obsession. But the people in the tunnels under the city call him their king—and when he looks at me, something wild and hungry flickers behind his eyes. He says he needs a wife on paper. I know he's lying. The way he stares at my wrist, at the birthmark I've always hidden, tells me he needs something darker. On our wedding night, he finally tells me the truth: my mother's death, his curse, and my brother's disappearance are bound by the same blood contract—and I just signed myself into the center of it.
