This was an excellent book and I can't wait to read the rest of the series. Cinder is set in a dystopian future where robots are second-class citizens, and robot-human hybrids are even lower than that.
As the name of the book would suggest, this is a modern re-telling of the fairy tale, Cinderella. I liked that it didn't borrow so heavily from the original that the plotline became obvious. This book will keep you guessing until the end and leave you wanting more.
I give this book 6 out of 5 stars.
