And Sanderson does it again. What a fun, well-written, entretaining and at the same time thoughtful book. I have to admit it indulges a little on intertextuality in moments, but I don't mind. This is a solid story about fighting crime, adventure, a world changing with technology, friendship and how life experience can change you, and it will prod you to read the next books in the Mistborn series. I definitely recommend it.
