The Lunar Chronicles - Cress By Marissa Meyer

CRESS grew-up as a prisoner. With only netscreens for company she's forced to do the bidding of the evil Queen Levana. Now that means tracking down Cinder and her handsome accomplice Emperor Kai. But little does Levana know that those she seeks, and the man she loves, are plotting her downfall . . .

As paths cross and the price of freedom rises, happily ever after has never seemed further away for Cress, Scarlet and Cinder.

This is not the fairy tale you remember. But it's one you won't forget.
