The real genius in Sanderson lies not just in his ability to create rich worlds, but to do so tremendously concisely. This isn't just a good thing on its own - I actually think it makes for far more wonderful books, particularly in the Cosmere. It's not surprising that Elantris, Warbreaker, Tress and the other standalone novels are my favourite in the franchise - as impressive as The Stormlight Archive is (so far) there's just so much of it that it sometimes falls under its own weight.
Yumi is another great example of this effect. In just 500 pages we have yet another planet in the Cosmere, with a rich yet easily accessible system of fantasy and lore, and characterisation aplenty - all wrapped up in a decent romance to boot. There really is little to complain about here.
And yet it doesn't quite reach the upper rankings, not because it's not good, but more because it's not as good. That's no mean feat for sure - make no mistake, I enjoyed Yumi a lot, it's just not my favourite. Otherwise it's just the ticket to tide me over till the next book in the Cosmere... coming up next.
