Typical

Cinderella fusion AU where the prince isn't all that charming, the [step]family is more vexing than evil, and the star of the show never quite makes it to the ball.

AU description: Harry may or may not be the boy who lived. (He's rich either way, and the Potters were a noble family, I think. Plus, Quidditch star.) There's no particular Death Eater taint to families, and whether or not Voldemort existed, he definitely never came back. Hogwarts Houses are each their own institutions, and the inter-house rivalries are now school rivalries.
