Deadly Oath by M. James

The sheriff standing on my doorstep should make me feel safe. So why does he feel like another threat I need to escape?

Six weeks ago, I was a Bratva princess—the only daughter of one of Chicago’s most powerful pakhans. Then my father’s rival tried to steal me, and that’s when everything changed.
Now, with a new last name, a strange new home, and an uncertain future, I’m lost. That is, until Sheriff Kian Brady shows up on my front step, telling me he’s here if I need anything.
Gorgeous, chivalrous, and with a dangerous edge he tries to keep hidden, Kian is everything I never thought I could have in my life. And soon enough, my initial attempts to resist his charms end with me swept off of my feet.
He wants me safe. He wants me as his wife. Whether it’s real for him or just for my protection, I can’t tell, but with every passing day, it feels more real to me—until I discover that the vows he swore hide secrets I never saw coming.
My new husband made an oath. But it’s not the one he said at the altar.
