For me, the plot slows down a tad in Lord of Chaos. All the events in the story seem more disconnected and don't flow as well as in the other books. However, Robert Jordan always brings the story round to a great ending.
The male narrator seemed to use exclusively whining voices whenever his portion included female characrers. Ridiculously over the top whining. He did a better job on earlier books. It made listening to the portions he narrated unpleasant.
My husband had been after me for years to read The Wheel of Time series. Audible makes it so much easier to do! I've thoroughly enjoyed how Ms. Reading and Mr. Kramer read the stories too. I recommend them to all my friends.
