Scarlet, a retelling of Little Red Riding Hood, introduces three new characters to the Luna Chronicles: Thorne, Scarlet and Wolf. The story alternates between Scarlet, as she tries to rescue her grandmother from some psychopaths with Wolf's help, and Cinder, as she tries to escape from prison with Thorne's help. This book will only make sense to someone who has already read the first book in the series, Cinder.
It's a fun book, with much action and some drama. Meyer's writing was noticeably better in this book than it was in Cinder: the conversations are less stilted, the action better described, and the characters more well-rounded. I enjoyed it, and am looking forward to reading the next in the series.
