My Secret Master (A Dark Billionaire Romance)

He said he would become my Master. And he meant it.
Life has never been easy. Struggling was just the name of the game.
So when billionaire Seth Hart took me from rags to riches, I was stunned.
He's confident, powerful, impossibly sexy. I thought he was perfect.
Then I discovered his dark secret.
No one would have guessed what wicked things he's hiding in his mansion.
If he finds out that I know, he'll ruin my future— and me along with it.
I know I should run, but I can't resist him.
Those warm lips, firm hands, the way he makes me beg...
He wants to keep me.
And Seth Hart always gets what he wants.
