We Free the Stars by Hafsah Faizal

The battle on Sharr is over. The dark forest has fallen. Altair may be captive, but Zafira, Nasir, and Kifah are bound for Sultan’s Keep, determined to finish the plan he set in motion: restoring the hearts of the Sisters of Old to the minarets of each caliphate, and finally returning magic to all of Arawiya. But they are low on resources and allies alike, and the kingdom teems with fear of the Lion of the Night’s return.

As the zumra plots to overthrow the kingdom’s darkest threat, Nasir fights to command the magic in his blood. He must learn to hone his power into a weapon, to wield not only against the Lion but against his father, trapped under the Lion’s control. Zafira battles a very different darkness festering in her through her bond with the Jawarat—a darkness that hums with voices, pushing her to the brink of her sanity and to the edge of a chaos she dare not unleash. In spite of the darkness enclosing ever faster, Nasir and Zafira find themselves falling into a love they can’t stand to lose…but time is running out to achieve their ends, and if order is to be restored, drastic sacrifices will have to be made.
