In this stunning sequel to Cinder, Scarlet Benoit is a young French girl, eighteen years old, and nothing to those around her but a nuisance. Her grandmother has gone missing, and the police say she either ran away, or committed suicide, but Scarlet knows better. She can get no one to listen and help, until she meets a mysterious street fighter named Wolf, who becomes a friend, and soon, more than just that.
Cinder is just an ordinary cyborg in a dystopian future Beijing. She lives with her stepmom Adri and her step sisters Pearl, who doesn’t like her very much; and Peony, who loves Cinder very much. She works at a small market mechanic shop she owns, and fixes people’s port screens, droids and other mechanical things. She thinks she is nothing special, with her mechanical “monstrosities”, but one day she gets a unusual customer that may just change her life for the better.
