 This was fun but I enjoyed the first installment more. Maybe it's because I got attached to Cinder during the first book but I liked the Cinder chapters better than the Scarlet ones (which kind of defeats the purpose of a book called 'Scarlet', I suppose). I just felt like the story of Scarlet dragged on until the last third of the book when it finally started to pick up pace. I'm also not a big fan of Wolf, to be honest and overall found the story of Cinder's and Thorne's escape to be more compelling than Scarlet's search for her grandmother. But overall, this was still a solid sequel to Cinder which expanded the world and advanced the plot. I can't wait to see the the four of them interacting more in the next book!
