Sinfully Yours' Step-Brother of Mine

Sinfully Yours' Step-Brother of Mine

I was just trying to survive my toxic family when I had the hottest one-night stand of my life. Then I found out he's my new stepbrother. And a mafia don. Demetrio DeLeon is dangerous, controlling, and completely off-limits. He's also the only man who's ever made me feel alive. Every stolen touch is forbidden. Every heated glance could destroy us both. But when his enemies come for me, I discover I'm not just some college dropout caught in the crossfire. I'm the missing daughter of the Russian Bratva's most feared pakhan. The girl whose kidnapping twenty years ago started a bloody war between two mafia empires. And now that war is back, with me at the center. Demetrio says he'll burn the world down before he lets me go. My biological brother Alexei wants to take me home to Russia. And I'm caught between two families, two worlds, and a love so consuming it might just kill us all. Some secrets are worth dying for. This one might cost me everything.

Tempted by my brother-in-law.

Hazel Skai didn’t marry into the powerful Varyn family for love. She married to survive… and to find the mother who abandoned her.
