Heavy Crown (Brutal Birthright, #6) by Sophie Lark

She was a temptation he couldn't resist...
I saw her being stuffed in a trunk: Yelena Yenina, only daughter of the most vicious Bratva boss in Chicago.
The Bratva hate my family. They burned my uncle alive. I should have left Yelena to her fate...
But she fought like a Valkyrie. Gorgeous, ferocious, and unbreakable.
