The second and final interlude before the next book in the series and we are once again sent back to Scadrial to have fun with allomancy. This book is probably the most different of the ones I read so far, being presented as a text having been written in the universe itself. I will admit that the meta pushed my ability to suspend my disbelief but it was all over before I knew it so it's hardly a big complaint. What is a complaint was the overused footnotes by the "editor" used as a kind of crutch or foil to make some prety cheap gags, kind of like inapproriate hashtags.
But it was different, and that's one of the nice things about the Cosmere.
