Stroke of Midnight by Stella Dawn

Cindy isn’t interested in princes and thinks that happily ever after is nothing more than a fairytale. But the other shoe is about to drop, because the only way for her to rescue her stepsisters from their wicked stepmother is to sneak into the ball and outmaneuver the one man she cannot stand — the arrogant, selfish, and sexy-as-sin king.
