Brandon Sanderson is a master storyteller. This novelette was a steal at 99 cents. 
 I gave it 3 stars because it, as many short stories do, gives an ending I feel isn't very satisfying. Short form is great for telling a scene, but this length - and I think my Kindle said it was 44 pages - is long enough that I expect a more emotionally satisfying ending, and I didn't get it. 
 Still, if the story is about the ride, and not the ending, then this would get 4 or maybe 5 stars from me. It's awesome from the get-go and barely lets up. 
 But as it stands, I only liked it, instead of thinking it was one of the greatest things ever done. 
 I still recommend it though. 
 And as I go through my reading list and see how I've rated other books, I must confess that my rating system needs some work. This is better than some other stories I've rated higher. I suppose it has to do with expectations. I expect more from Sanderson than I do most authors.
