Sinful Obsession by Brook Wilder

I agreed to marry a bratva boss in exchange for him protecting my mother.
The moment my paths crossed with Arsen Isakov, normality went out the window.
I went along with his twisted plan of a fake marriage – all to keep my mother safe – and walked down the aisle towards him with my head held high.
Nothing prepared me for becoming pregnant with his child.
Nothing prepared me to learn the dark truths of our shared past.
When I found out, I did the only thing I can: I ran.
Now, he’s coming for me.
And he won’t stop until he has me back—back in his life, and back in his bed.
But I know something that I can’t tell him.
Something that, if left alone, will destroy him.
Something that, if he finds out, he’ll destroy.
Something that, if destroyed, will break me.
