This is probably my favorite book in the Onyx Court series. It’s a much tighter story, and I got the sense of how closely the mortal and Faerie worlds influence one another, even if the monarchs aren’t tied. The ending made me want to read more about the Court and their reactions to the oncoming Industrial Revolution, what happened with Lune and the future of the Onyx Hall and the London fae. I also liked Abd al-Rashir, and the glimpse of non-European fae and their cultural differences. In all, a fun read and I would love to see more from Marie Brennan’s world.
