Wicked Altar by Jane Henry

I’ve hated Cavin McCarthy since the day he made me cry in a school cupboard.

He was my tormentor—the cruel bastard who turned my name into a joke and my life into hell.
Now? He’s my fiancé.
An arranged marriage neither of us wanted, brokered by families who deal in blood and power. I’d refuse if I could. But my sister is dying, and the McCarthy’s hold the key to saving her life.
So I’ll walk down the aisle. I’ll say the vows. I’ll become Mrs. Cavin McCarthy.
But I’ll never forgive the arrogant jerk.
Except… the monster I remember isn’t the man before me now. The boy who destroyed me has become someone who’d burn the world down to keep me safe. Who touches me like I’m something precious instead of ruined. Whose rough hands and rougher words unravel every defense I’ve built.
When his fingers wrap around my throat and his voice goes low in my ear, I’m not thinking about revenge anymore…
I’m thinking about surrender.
And in the McCarthy family, surrender might be the most dangerous thing of all.
