A solid sequel, but less innovative than the original. Scarlet suffers from too many plot lines and 3rd person limited narrator. While Cinder had only Cinder and Kai to keep track of, this one keeps those two and adds Scarlet and occasionally Wolf and even an ominous Levana chapter. It makes it difficult to become invested in these new characters. 
 Speaking of which, Scarlet's personality is fairly flat. Her insecurities aren't as evident as Cinder's and she kind of plays the hero without thinking. Her decisions are stupid, yet she does not explicitly suffer because of her stupidity. Her relationship with Wolf has very little tension and was of little interest to me. 
 There were some good twists, but there were also many moments that I just felt stupid for not seeing coming. If I had been paying more attention while reading, I imagine I would have caught them. 
 I may pick up the sequels, but I'm in no hurry to.
