A quick and tightly-written read, with some beautiful illustrations. 
 The protagonist is great. Here we have this middle-aged mother who really just wants her sons back, who ends up becoming a legend through a combination of inflated rumor and her own determination. 
 My one complaint is that it feels more like a snowflake-draft than a completed work. Not that it feels in any way unfinished--goodness, no--but in that it feels like there was a great deal to be expanded upon. 
 3/5. I'm interested in picking up the other novella in this collaborative world.
