This one was my favorite of the series so far. This was partly because almost all of the backstory is established now, so it's less learning about the universe Meyer has created and more watching the action unfold as Cinder and the gang try to save the world. I also enjoyed the romance in this one a little more because Thorne was a more enjoyable character to have someone swooning over than Kai and Wolf. It's been fun to watch him evolve into more than just a shallow "Prince Charming." There were still some parts that had me squirming, but that's just YA romance for you. 
 Looking forward to Winter minus the fact that it's 800-something pages!
