The Jasad Crown (The Scorched Throne, #2) by Sara Hashem

In the thrilling conclusion to the Egyptian-inspired Scorched Throne duology, a fugitive queen may be the key to restoring her lost kingdom of Jasad, but it could cost her everything and everyone she loves.

Held deep in a mountain refuge, Sylvia has been captured by the Urabi, who believe she can return their homeland to its former power. But after years of denying her legacy and a forbidden alliance with Jasad's greatest enemy, Sylvia must win the group's trust while struggling to keep control of both her magic and her mind.

In the rival kingdom, Arin is caught between his father's desire to put down the brewing rebellion and the sacred edicts he's sworn to uphold. Arin must find Sylvia before his father's army, but his search will call into question the very core of Arin's beliefs about his family and the destruction of Jasad.

War is inevitable and Sylvia cannot abandon her people again. The Urabi plan to raise the Jasadi fortress, and it will either kill Sylvia or destroy the humanity she's fought so hard to protect. For the first time in her life Sylvia doesn't just want to survive. She wants to win.
The fugitive queen is ready to come home.
