Cinder: The Lunar Chronicles
By Marissa Meyer
A cyborg named Cinder is a gifted mechanic. When her life suddenly becomes intertwined with Prince Kai's Cinder finds herself in the middle of an intergalactic struggle. Cinder must uncover secrets about her past to save the whole world's future.
I recommend this book series to people who like classic Disney tales (because there is also one about Little Red Riding Hood and Rapunzel) as well as sci-fi. And to people who are older because it has mature content. It keeps you hooked all the way through.
