Promised to the Pakhan

I'm to marry the enormous Russian Milos Vasiliev, if I don't it will fall to my little sister. My father tells me I'm lucky the head of the Russian Bratva in Chicago is willing to take me. The powerful man could have anyone he wanted. I don't feel lucky. The terrifying, scarred man just wants to secure the relationship with the Chicago Outfit that my father is the head of. And oh yeah, he's ready for children. He doesn't want my heart, just my body. What happens when I wind up giving him both?  This is the first in a standalone series. It does not end in a cliffhanger.
