Cruel Control by Candace Wondrak

Sometimes the worst monsters in the world are the ones we let close.

Daddy keeps me locked away. For my own good, he says. The world is a dark and terrible place, full of people who will take advantage of you, hurt you… maybe even kill you. I don’t know what he does, only that his clients are of the rich variety.
But one day he doesn’t come home, and I wake to find a stranger in my room.
Whisked away, stolen to a house on the outskirts of Midpark, I’m no more than a pawn, something the devil himself can control. Daddy crossed the devil, and now I’m to pay for his sins.
What is the devil’s name, you ask?
Markus Scott. And Markus will not stop until I fall in line.
This innocence of mine has no place in a hell like this.
