Aaahhh...the joy of finishing a book in a day.
Okay, that's probably not a great review, but definitely says something about the book, doesn't it? To be honest, I did read the last 150 or so pages of the book just so that I can say that I finished it a day, but still.
Not as good as the first three Mistborn books, but with so many things yet to come, so many plot lines still to unfold, I think the next one will be more exciting.
Also, I like the way how Sanderson keeps giving references to the first three books. Kind of feels awesome to get those references.
