2/9/16: Enjoyed this much better the second time! I think that I originally didn't like this as much because I was expecting another epic novel, on the scale of the first 3 in the series. I was disappointed. This time, however, going into this knowing it's a crime novel with a lot of set up for books further down the line let me enjoy it more for what it was. And it was so fun! I love the buddy dynamic between Wax and Wayne, the chemistry between Wax and Marasi, and the general sense of humor the whole thing has. I also love knowing that there is a (view spoiler)[ greater conspiracy at work which I'm sure will be worked out in the usual Sanderson way (you know, like 3 books later with various earth shattering revelations interspersed throughout) (hide spoiler)]. Greatly looking forward to continuing the series. 
 1/30/16: re-reading in audio format, read this as a book when it came out a few years ago. Now that the next couple are out I want to do this again because I don't remember it very well.
