Fourth book of the Ravicka series which follows two different investigators of the mysteries of Ravicka's shifting architectures & geographies. Explores rather than explains the mysteries of Ravicka. I notice that all of the characters that the books follow have a sort of solitude. Although they all have many friends & social connections in the community who they interact with, none of them really work alongside anyone else, & no one seems to live with anyone else, whether a spouse or a roommate. Although most of the characters are artists of all kinds, there's no one who really has to collaborate, such as a musician in a band or orchestra, or a player in a theater company. Is that the experience of all us artists & dilettantes of this atomized time? I find that I often gravitate towards solo pursuits, even though I'm more productive & have more fun working in a group. I really hope Gladman finishes the Ravicka novel about grasses that she mentioned in the afterward. I hope to return to Ravicka sometime, & a new novel would be just the occasion to re-read all of the books.
