I have read pretty much every epic Fantasy published in the last 20 years, including self published ones, and this series towers above all of them.
So you don't feel like you are putting money on the line, create a Gmail account and get an audible credit. Download Way of Kings, good sir. In my experience, for a book this long, you usually see huge battles between partisans: Infinite Jest, Gravity's Rainbow...you get the point.
I have thrust this book on more friends than any other in my life (that's my habit), and I have yet to see someone get 20% in and not be thoroughly engrossed.
That said, Words of Radiance, imo, is far superior, although I have no idea how the story can really continue at this pace for 8 to 10 books.... Frankly, I'm baffled how the third book can be anything approaching what we who treasure this series would want... The POV is going to be largely focused on a character that we don't really want as a protagonist, and, again, the pace is so frantic at this point that I am hesitant to recommend this to people until the third book comes out.
It's kind of ironic, since I was just as engrossed by Wheel of Time when I was a kid, as were many of my peers... And I dread that it's going to be a bit like WoT books 5-8, though I actually loved those books. I just know almost all those peers set it aside until Brandon came in and finished it up.
Apologies for the length and lack of lucidity; I assure you, Brandon may write as much, but for some reason that is beyond my ken, he isn't tedious.
Hope you take the audible challenge, but elsewise wish you well,
