I love it. I loved all of Brandon Sanderson's works so this is no surprise. It's fun and exciting, as all Mistborn novels are. There's plenty of character development to go around (Marasi and Steris, in particular), and the world-building is perfection as usual. 
 This book's not perfect, though. Wayne's POV's, which never bothered me before, are rather tonally jarring this time around. It's more random than usual, to the point that it detracted from my enjoyment of the book. The humor isn't always in point, and sometimes it hampers the smoothness of the dialogue. I think the book could have used another round of checking by the editor, and I hope the next Mistborn novel is more polished.
