I love the wheel of time. Best get that out of the way because i would probably give a book 5 stars simply because of the series and not for the actual book.
With the Gathering Storm that is not the case. This is a fantastic start to the "final trilogy". The book focus' on Rand Al'Thor and Egwene Al'Vere. I presume it will move onto the other major characters (Mat and Perrin and Elayne) in the next book.
This book FINALLY has a story that looks like there is going to be an ending for the series. The huge problem with the series was that it appeared Robert Jordan did not know how to finish it. That is shown in books 6-10 of the series. They tend to drift on and lose any form of plot.
Now that Robert Jordan has passed on Brandon Sanderson took over and has done a fantastic job. The great news is that this book finally brings some sort of finality to the series. The bad news in you do need to read books 6-10 to know what is going on.
In short, The series in fantastic, but losings some stars in the middle. This book brings the series back to its best.
I can not wait for the final two book to come out. Anyone looking to purchase this would probably feel the same.
