4 stars.
Remember how I read Cinder and found it pretty meh? Well, people were right. The next book gets significantly better. I liked Scarlet better as a heroine in pretty much every way. I was really nervous about how the romance would play out when I found out the dreamy guy with the green eyes was named Wolf (and Scarlet is Little Red Riding Hood). Hoo boy, that could have gone really badly. But it was fun and tense in all the right ways, and it turns out I like Cinder better in an ensemble cast than I do as the single star–much like Tony Stark, actually. I mean, for entirely different reasons.
