Note that this is part of a trilogy that hasn't had the third book released and its been 10 years. I doubt it will be out in another 10, so tread with caution if you don't like to wait on a book release. Amazing book though.
Anyway, it may be for the best (think Matrix 3 and 4).
"The Slow Regard of silent things" is also a beautiful book that builds slowly and expands a little detail of the world of "The name of the wind"
