Red Lace Manor by Erin Mersey

Four masked men–One sinister game.
If I survive until morning, I’ll be ten million dollars richer.
The only problem is these men don’t just want my life–they want everything.
They need to break me, to own me, to ruin me in ways I’ve only dreamed about.
I thought making it until morning would be a piece of cake, but what if their game doesn’t end at sunrise?
