A Prayer for the Crown-Shy is the second novella in this series; if the first book focused a bit more on Sibling Dex's journey, this book switches to look at Mosscap and Sibling Dex's shared travel to small towns across Panga. Their journey is presented as a series of vignettes which fill in worldbuilding details and bring in a number of different themes. Because of this, I think this book feels more winding and broad than the first one, but it's still just as endearing.
There's just so many delightful Mosscap moments: Mosscap being newly excited about every tree along the road; Mosscap waking up Sibling Dex up at a godawful early hour because they're just too impatient to discuss a book and then continuing that discussion while Dex attempts to pee; Mosscap bursting in to congratulate Dex about having sex.
Reading both of these back to back makes me appreciate how much the second book's ending is an echo of the first's, where each resolves an uncomfortable question that has been hanging in the air between Dex and Mosscap while also getting to the heart of their own struggles (that continue to hit me right in my own insecurities).
