The book follows three main plotlines: Having won the throne of Illian, after his defeat of the Forsaken Sammael, Rand al'Thor turns his attention to dealing with the Seanchan threat to the West.
Having found the Bowl of the Winds, Nynaeve al'Meara, Elayne Trakand and Nynaeve successfully attempt to use the Bowl to reverse the adverse weather with the help of Sea Folk Windfinders and the Kin.
Perrin Aybara leads a covert mission for the Lord Dragon...but, does it all end well for the Wolfbrother?
Aes Sedai politicking reaches fever pitch in this installment. Equally intriguing to watch is the struggle of wills between the Aiel Wise Ones, The Sea Folk, and the Aes Sedai.
Once again the author displays his unrivalled character development skills in his creation of the new character Cadsuane. Her approach to guiding Rand al'Thor as opposed to Moiraine's persistent close-marking and the bullying employed by the other Aes Sedai is quite interesting to watch.
I think this series' magic system is greatly underrated. There's a whole lot of structure to it, although the author only explains bits of it in each book.
This book marks the point where the author begins to lose track (according to most WoT fans). I used to think so too, until I embarked on this reread of the entire series. I think it's all dependent on what one enjoys most in the books. If you're the type who doesn't mind watching top-class character building at the expense of plot progress, you'll find it greatly interesting.
