The most Cosmere-heavy of the Year of Sanderson books, and the worst. The book strongly feels like a transitional issue of a comic, in which a character needs to get from one place to another and we might as well have a story to get them there. The afterword indicates that this was the case and that Sanderson felt that he should have a more Cosmere-focused story to add to his year.
Usually Sanderson gets through these less interesting entries with fun concepts and characters,  but this book just doesn't have either - The main characters are dull and the world, while full of all the usual Sanderson high concept magic, had no real urgency and didn't connect with me - Giving most of the characters incompatible and difficult names to remember did not help. Nor did having one ineffectual villain and another which doesn't do anything because they're just being set up for another story.
All this leaves the Year of Sanderson to end on... a filler episode. Weird.
