The title for this review may not make sense until you've read the book - so go read it now!
Sanderson is a true master of creating characters, worlds, and magic systems. Each of these is so unique and is told in such a genuine way that I find it hard to believe that these people and places do not truly exist.
The book may seem short - but don't let that fool you. It is packed full of goodness and Sanderson can build the type of story in a hundred pages that it would take most other authors 600 pages to accomplish.
