This book is obviously based on Cinderella. There is a mechanic named Cinder who is a cyborg. Her parents died and so did her stepfather. Her stepmother treats her like a “slave” and makes it clear that she doesn’t like Cinder. She is the best mechanic in New Beijing, so Prince Kai comes to here to ask to fix his andriod before the ball. As Cinder tries to make the prince proud, her stepsister gets the plague. Cinder’s stepmother blames this on Cinder, and volunteers her body as research for the plague. This book makes you want to read the second because it’s SUCH A BIG CLIFHANGER!!
