Dreams That You WishA Dark Cinderella Retelling

Sin had always dreamed of a night worth living—a night at the infamous castle ball, filled with dancing and debauchery.
When her wish comes true, and she flees the prince's chambers in her glamoured glass stilettos, she learns a very important lesson:
Dreams don't die.
They degenerate.
Instead of the fairytale she imagined, Sin's night of revelry becomes a nightmare.
A prince with secrets.
A witch with a past she cannot remember.
A king, who views her burgeoning abilities as a threat, a reason for execution.
Magic screams beneath her skin to end them all, and she'll do anything not to obey.
