A Dead Djinn in Cairo by P. Djèlí Clark
I thoroughly enjoyed A Master of Djinn and my library had "A Dead Djinn in Cairo" on audio, so I picked it up. The setting is a steampunk 1912 Cairo in a world where magic has been discovered/released. With the help of the djinn, Egypt has pretty much thrown England out.
Fatma is sent out to investigate the apparent suicide of a strong djinn, but nothing's ever that simple is it. I enjoyed meeting Fatma again and seeing how her relationship with Siti started. The plot was fun, full of djinn and clockwork angels and ghouls. The main problem, the thing Fatma has to stop, becomes a problem again in the first full-length novel in the series, so I'm not sure if I'm glad to see how it originated or disappointed that the same "machine" is used in both....
