Cinder by Marissa Meyer: Lunar Chronicles

Imagine fractured fairy tale meets science fiction and you have the Lunar Chronicles.  In this first book by Marissa Meyer, Cinder is a cyborg mechanic.  Her stepmother is nasty, but not her biggest enemy. Queen Levana from the moon has that title.  Cinder runs afoul of her at the Emperor's ball.

The Lunar Chronicles are filled with strong female characters.  Scarlet (Book 2) is a retelling of Little Red Riding Hood.  I recommend this series for middle school and above.
