Dawnshard seems far more significant to the Cosmere than it should be, considering it's actually a "novella". At 150 odd pages its a quick, yet dense, read, and in many ways raises more questions than it answers. That's not to say that anything in the Cosmere is irrelevant, it's more a warning that one shouldn't underestimate this book.
Everything else remains standard Cosmere fare: the novella is well written, the action dramatic, the progress generous and the plot tantalising (which isn't necessarily great for those of us who need answers). It's vital in both the Stormlight Archive and wider Cosmere, which I suspect will be par for the course going forward.
