I like the story, I think I would have loved the book if Sanderson had published it as a regular novel, instead of being published separately as graphic novels. But sadly that is the case, so I'm not enjoying these White Sand volumes very much.
To start with, it's a bit confusing, so much world building and magic to explain with so little text, most of it dialogues. And I've never been a fan of the artwork, the details most of all. But what they did with this last volume, using a different artist for the last chapter, was... not cool.
Of course I'll read the last installment, because it's an important part of the Cosmere, but I can't imagine how they will tie every loose end in just one more volume. Only time will tell.
