Brilliant writer. His Wheel of Time series is simply superb, and in my opinion, comparable to Tolkien. He created a real-seeming world, with (mostly) real-seeming characters.
My only complaints with his series would have to be a couple of his newest books, mainly because of the slow pace. I do think he has himself "caught" currently, but I hope his next books are better. I'm still a loyal fan, and very much in awe of his writing abilities
