Pure Sanderson. This book blends the well constructed world of the Mistborn with a refreshing new world very akin to a Western. And creates two fun characters with unique personalities to fill it out. Not content with creating two cowboys with magic powers, he creates some additional supporting characters that are intersting, strong, smart, and nuanced. No mere ornaments to the main players.

All in all, if you like Sanderson, you'll like these books.
