BEAST A Dark Beauty and the Beast Retelling

Ellie came to me with a bargain. Her life for her father's, but I didn't build my empire by letting debts go unpaid. You owe me, you pay. End of story. 
But this girl didn't just walk in shaking and begging for mercy- no, Ellie charged in demanding her father's freedom. 
I take her deal, adding my own conditions, of course. I'm not a good man. I'm a beast, and my hunger for her will be fed. I will possess her.
But there's more at play here than just the love of a daughter, the possession of a beauty. Secrets that won't stay buried. Dangerous desires needing to be explored.
Outside forces want in, want to take what's mine. And when Ellie finds out the secrets of her own past, she'll need to decide. What exactly is she willing to risk for love.
