This was a nice tie-in with the Stormlight Archive novels, although you don't have to have read them to enjoy the story. However, there are a lot of Cosmere references in this one, and if you aren't at least a little bit familiar with the lore, you're missing out on many of the little details.

Since I haven't read all of the Cosmere novels yet, there were points in the story where I wished I knew more of the background, to understand the references. Also, it's been some time since I read the Stormlight novels, so I couldn't remember some of the stuff where I thought "wait, that sounds familiar..."

Still, absolutely a recommendation for every Sanderson / Cosmere fan out there!
