Sinful Cinderella

I'm not who they think I am. A docile girl who meekly obeys her stepmother and stepsisters. Some kind of sick angel who cheerfully bears their mistreatment. That's what I WANT them to think. Because then they won't suspect what I'm really up to.  The ball, the prince - it's all part of my plan to come out on top. Stepmother and her demented daughters will pay for every floor I have scoured, every sneer I have borne. They don't know about the white magic, how I use it to enhance myself. They can't see that my heart is black as midnight, rotten as a poisoned apple.  They're about to find out.
