Questioner
Why?
Brandon Sanderson
Well, number one, I had been following that series for 20 years, and I was finishing off the writing of an author I respected a lot, and trying to fill his shoes, and not being able to do it because no one could, and the end of a journey. Every other book I've finished, I know if I wanted to I could go back and write more about those characters. Wheel of Time, I can't. It's done. It's not mine; I can't go write another book about Mat or Perrin or anything like that. So there's a finality to finishing that book that I haven't had with any of my other books. And then in addition, logistically it was a very difficult book to write.
