Sanderson continues to astound. this is a really great story. Totally clean, but not childish. And quite thought provoking. The magic system makes sense, I think, but I haven't really grasped it yet. The concept is totally fascinating, though. It basically took me the entire book before I was starting to comprehend how things work. I'll have to read it again, and keep waiting for Brandon to hurry up with the sequel. 
 Great characters, somewhat Dickensian in style. Which fits well with the Steampunk Victorian atmosphere. the plot is rather unique, it swells to the world saving/cataclysm prevention proportions one expects from fantasy, all while remaining inside a murder mystery like setting. 
 I'm definitely expecting great things from this series when Sanderson finally finishes it. There are lots of questions.
