Brandon Sanderson is a high fantasy author. His works include the Mistborn trilogy, The Stromlight Archive saga and stand alone novels Elantris and Warbreaker. He was also chosen to continue the epic (in every sense of the word) The Wheel of Time (WoT) series written by Robert Jordan after his (Jordan’s) death.
