The Barbarian (Conquerors #6)
Georgia Fox

Amias knows Stryker doesn't want a wife, but he needs her bride purse and he's just desperate enough to take her on, reputation and all. Whatever is required to claim the haughty lady's dowry, this ruthless warrior will do it.
Except one thing. He'll never give his heart.
Undaunted, Amias strikes a bargain with her barbarian. After all, he has other parts to share, even if his heart is out of bounds. He may think he's unlovable, his manor uninhabitable for a lady, but she hasn't earned the name "Ami the Unbreakable" for nothing.
