Jessamine was born to be a leader of her people, but when a deadly plague strikes her kingdom, she's forced into a political marriage in hopes of saving them. But the wedding ends in betrayal—she is murdered by her new husband, and her throne is lost.

But death isn’t the end for Jessamine. Her spirit meets the Deathless One, a powerful god who yearns to return to the living realm. He offers her a deal—help bring him back, and in return, she’ll reclaim her life and her throne. But the Deathless One is a dangerous trickster, and with their bargain is sealed in blood, Jessamine has to be careful. As Jessamine and the Deathless One work together, their bond grows stronger—and more complicated, and Jessamine soon realizes that the throne she wants might not be the one in the mortal realm.
