Well, that got weird. But in a good way? Sometimes I feel like Sanderson just throws a bunch of word spaghetti to the wall, hoping it will stick. He's good enough that most of the time it works, but sometimes there are things that feel a little out of place. ((view spoiler)[For instance, the scene at the end with Calamity didn't have nearly enough resonance. I understand that he was setting things up for the next book, but the scene didn't ring true for me. (hide spoiler)]) That being said, there was a lot I liked about this. It retained the energy and humor of the first book, while also taking some big steps (and a big move) away from Newcago. The David/Firefight scenes positively crackled and the new Big Bad was pretty terrifying. All in all, I'm as miffed as a hen on a race track* that I have to wait a whole year for the last installment. 
 *Because if a hen ended up on a race track, it would probably be really annoyed that it wasn't where it belonged. I think David would approve.
