This has a completely different twist! I don't know how I didn't guessed when I started reading it, maybe I was just starved for books to read.
This story is a sci-fi Cinderella story. But anyways, this book is about the future, a cyborg orphan who lives with her stepmother, feels truly lonely in the world. She lives in a world that depends on technology, and is ruled by royalty. Where the Lunar people watch from above, waiting for their next move. She runs a shop in the market, she is a mechanic, a repair-your-technology mechanic, not the car one.
Cinder lives in New Beijing, where the "blue disease thrives". Cinder's world comes crashing around her as she try to survive in a world where she is an outcast, in many ways, some which she doesn't know. Cinder is now stuck in the middle of things, whether she likes it or not.
This is book one is the Lunar Chronicles.
I think there are about four books, she lists them in Cinder.
You seriously need to read this, I don't care if you're a girl or a boy, teenager or an adult. You need to read this!
P.S If you haven't gotten the hint, this is my new favorite book :D
