I'm giving this book 5 stars over the customary 4 star rating I would have simply because the "wrap-up" of the story is so complete! I don't know if I can explain this better, but Sanderson manages to tie up every single loose thread through all 3 books in this final book.

There are some minor slip-ups eg: When Vin is metal-less and fights Marsh (Yomen's chambers), she pulls a vial from him and recharges herself. Then she proceeds to burn duralumin, something that Marsh would definitely not have, because Inquisitors cannot burn it , but on the whole, I'm really impressed with Sanderson's ability to explain everything in his world, making it seem plausible and enhancing the reading experience tremendously.
