Paying Off Her Dad's Best Friend

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

My dad stole a fortune from his best friend. Now I'm paying the price.

His former best friend offers me a choice. 
A) He can kill my dad.
B) I can agree to move in with him.
To save my dad's life, I agree to give him my body.
I never agreed to give him my heart. 
I think he's stealing it anyway.
