Sibling Dex guides Mosscap through the human-inhabited lands so Mosscap can meet other people and continue its mission to find what humans need.

This second novella feels more disjointed than the first, more like highlights instead of the entire story; which is not necessarily a bad thing, but is just different compared to the Psalm for the Wild-Built. I do like that the relationship between Sibling Dex and Mosscap is more balanced in this second book. The highlight of the book is the relationship between the two main characters (I cannot express how much I adore their relationship which is important but isn't romantic or sexual) and the deep conversations they get into.
