Darkness surged in his veins. Power bled from her bones.

The battle on Sharr is over. The Arz has fallen. Altair may be captive, but Zafira, Nasir, and Kifah are bound for Sultan’s Keep, determined to finish the plan Altair set in motion: restoring the hearts of the Sisters of Old to the minarets of each caliphate, finally bringing 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 Arawiya’s darkest threat, Nasir fights to command the magic in his blood. He must learn to hone his power, to wield it against not only the Lion but his father as well, trapped under the Lion’s control. Zafira battles a very different darkness festering in her through her bond with the Jawarat―it hums with voices, pushing her to the brink of sanity and to the edge of a chaos she dares not unleash. In spite of everything, Zafira and Nasir find themselves falling into a love they can’t stand to lose . . . But time is running out, and if order is to be restored, drastic sacrifices will have to be made.
