Reading the novella 'A Dead Djinn in Cairo' is highly recommended before reading this. It was written before hand and does some introduction of character relationships and world-building which is helpful to know before reading A Master of Djinn.

This wasn't the best thing I've read, but the world is interesting. I could've used a glossary at parts because sometimes I felt the world-building relied a bit too much on prior knowledge of Egyptian history - particularly when it came to the political history of the more recent setting of early 1900s Cairo. I wish I could say I learned a bit more history, but for me it was hard to tell what was fantasized and what was not (besides the obvious Djinn). The mystery is a bit predictable. I liked Fatma as a main character, and her obsession with suits. I would probably read more in this world if the author wrote it, if the plot-line followed something a bit different.
