An interesting concept - a retelling of the Cinderella story, but set in a futuristic New Beijing. And with androids and cyborgs and other science fiction-y stuff. And Meyer does a pretty good job of maintaining the basics of the fairy tale - wicked stepmother, glass slipper, prince and ball, even the pumpkin coach and the fairy godmother. If you wanted to, you could read this as just another retelling of the Cinderella tale, and it would be good.
But, to be honest, I wasn't even thinking of Cinderella through most of the book; the fairy tale aside, this is a good science fiction dystopian future young adult novel, especially when you consider that it's the first book in a series. I do have a couple of quibbles about the amount of technical information on cyborgs and servo-motors and whatnot, and other reviewers are correct that the story is short on details about this future Earth, and about the history between Earth and the Lunars (moon dwellers). I hope future books in the series will fill in some of these gaps. But overall, this is a well written, entertaining piece of dystopian fiction.
