3.5 stars, but I'm trying to be consistent and round down when rating. I enjoyed reading this, if only because it gets me one step closer to my Sanderson completionist achievement, but it's definitely not my favourite. The middle of the book really slowed down for me, but then the author brought it all together in a great ending. All credit to Sanderson for his dedication to worldbuilding and new magic systems - as always, these were major strengths of the book. My absolute favorite part of the book was Nightblood! He (it?) was the best character hands down.
