The quickest read ever! It helps that it's only 172 pages.
I really like the premise of this book, I think it's unique. I was initially excited, since I heard it was in the same universe as Elantris, but this book has absolutely nothing to do with Elantris. I agree with one other reviewer: I wish there was more, since the idea is really unique, but the book is neither too long nor too short, something that is rare.
