This review is from: Words of Radiance: The Stormlight Archive Book Two (Kindle Edition)
I loved the scale of the books and the world looks like it will expand again in the future. The complexity is towards Game of Thrones but the level of violence is no way near as savage. This was a nice change after GOTs (which I love btw).
The fantasy world was sufficiently different from others to hold my interest and, similarly, the way magic works was unusual. The characters' motivations are very strong making significant changes in actions plausible.
Sanderson includes nice little interludes, quotes at the start of chapters and art work to give you clues, which I also liked. I think dedicated fantasy readers (who are in for the long haul) will like this a lot.
