At this point, I have read a lot of Sanderson books. There are two things that I love in his writing:

1. The complex world building
2. His ability to tie up all loose ends at the end of the book.

Warbreaker is no different. I enjoyed it thoroughly.

To nitpick slightly, I thought that the magic system could have been better explained. I still don't understand the role that color had to play in it. None-the-less, this is a small (by Sanderson terms) and quick airplane read.
