It took me over a week to read, where I normally rip through 2-3 books in a week. My hats off to Brandon Sanderson for writing such an involved story.
I was a bit confused at the beginning, much like when I read Warbreaker. His magic system is very integral to this storyline and he launches right into it near the beginning of the book, then bounces out to introduce all the main characters. The world he has invented is massive. Storms coming out of the East, great walls of water and wind. Entire civilizations, including plant and animal life hide out inside their shells, gripping the ground or hiding behind rocks in order to survive these storms.
It's a bleak existence, but one that is steeped in mystery, depth, survival, and triumph.
I can't wait for the next book in this series. I already bought the Hardback as well as the Kindle version. This is definitely one to read again.
