A Master of Djinn (2021)

Cairo in 1912 has ministries, police work and an imperial history transformed by the arrival of djinn. Clark makes that change explicit: this Egypt has escaped British domination and become a great power. Investigator Fatma's case moves through the machinery and inequalities of the resulting city. Choose it for magic that alters government and urban life at every level. It is a counterfactual Cairo, so keep its spectacular inventions separate from the history of the actual occupation.
