Brandon Sanderson's The Way of Kings conveys a much better sense of magical mystery than his Mistborn trilogy. In the Mistborn trilogy, I keep feeling that he's violated the mystical confusion of magic extolled in Tolkein's On Fairy Stories. The Way of Kings and Words of Radiance preserve the mystery. Yet that sense of mystery is somewhat dispelled near the end of Words of Radiance as so much is figured out by the characters and as these characters come into their powers. I'm hoping that he can preserve enough mystery that magic doesn't become as cut and dried as some of the code I write.
