I loved this book! :) It gets a five star rating! 
 At first, I was a little hesitant to read this book because it was based on Cinderella. Considering how the original tale works, I wan't sure if this book could interest me. I was proven wrong and I am so glad I was. 
 I love the direction this book takes. We have cyborgs, life threatening illness, power struggles, etc. This book is great. 
 Cinder is a great main character. She is funny, sarcastic, independent, and is willing to do whatever it takes to save the people she cares about. She does everything in her power to help find a cure for (view spoiler)[Peony since she was infected with letumosis, but she dies because Cinder was just a second too late. (hide spoiler)] 
 Even when she had an opportunity to escape from Adri, she sacrificed it so she could (view spoiler)[warn Kai of Levanna's plans after she was contacted by Cress. (hide spoiler)] 
 Kai was an excellent character. He was hilarious, kind, and willing to sacrifice his happiness for the sake of his people. I loved his relationship with Cinder and I was very upset when(view spoiler)[Kai found out she was a Lunar and had her imprisoned (hide spoiler)]. 
 Iko was hilarious and I hope she can come back. 
 Now, onto the next book! I heard Scarlet isn't as good as Cinder, but I will read it nonetheless.
