Ben knew that he wanted her the moment he saw her years before when his sister went out and got married for something that was unheard of in their circles. Love. They had worked together a few times but when the chance arose he made her a deal that she could not refuse. She only had to be his wife for a short time. He would then grant her a large payday.
