I love Scarlet as the main character, she is one of my favourites to read about. She shows so much determination and strength throughout the book. 
 I also couldn't stop reading because of the romance between her and Wolf, you know they aren't supposed to be together, but at the same time it feels so right. I was very happy with the ending of this book. 
 I also love the side story with Cinder as well, it's nice the characters from the first book aren't left behind, all the stories are intertwined.
