Though I really liked Vasher, I found myself identifying more with Denth in places. He was a riddle of a character, cloaked in his reticence, cryptic comments, and dark humor. This was not a man to be trifled with, and yet he worked great as a foil to Vasher's impatience because he watched, waited, and even helped... until it was time to hinder.
And I would be remiss if I didn't bring up Sanderson's gift for humor. Lightsong has some of the most amazingly sarcastic lines I've ever read in a fantasy novel. For example, fairly early on we learn about his desire to be the least active among the gods... "I try to avoid having thoughts. They lead to other thoughts, and — if you’re not careful — those lead to actions. Actions make you tired. I have this on rather good authority from someone who once read it in a book.”
Now that I've read some of Sanderson's own writing style and his voice, I will be very curious to read the two final books of the Wheel of Time series. From what I've heard, they may be closer to the tone of the first few books of the series, which I enjoyed more than later ones. And I may have to find Sanderson's Elantris series to catch up on what I've been missing from his earlier work as well.
If you like epic fantasy in a one-book package, Warbreaker from Brandon Sanderson is a steal. Be sure to pick it up at your favorite online or brick-and-mortar bookseller.
