The Orc’s Auctioned Mate by Veronika Kane

When the huge, terrifying orc bid on me, I thought my life was over. But could it be just the beginning?

On the midwinter full moon, I am dragged by bandits from the only home I know and stood on a chair in a tavern under the gazes of despicable men bidding on my innocence. But then the shadowy figure in the corner calls out the winning offer, and I realize he is like no one I’ve ever seen before.
Now I belong to Torvolk, Ranger of the Bloodfire Clan, and neither of us knows what this means. He’s taken me through the pathway in the standing stones to his world, where I discovered naught is as it has always seemed. Torvolk has a mission, and the longer I spend with my new keeper, the more I realize I might be able to help him.

The way he’s helped me.
