Cinderella-ish

Elliot is absolutely, positively in love with Prince Oliver. He'd do anything to be with him, even sell his soul to the devil so he could have one night to make him feel the same way.
But what if it doesn't work?
What if beauty, fabulous fashion sense, and undying devotion isn't enough to sway someone's feelings?
And what if it leaves him with a pissed off mother, a pissed off Prince, and a pervertedly handsome daemon who he's forever indebted to?
