When Ellaeva runs afoul of the Rahmyrrim High Priestess and finds herself imprisoned, the only man who can help her is the one she vowed never to see again—Lyram Aharris. But Ellaeva’s faith in her goddess is broken, and when Lyram refuses to abandon her to fate, she struggles to come to terms with what she has lost. Haunted by his broken oaths, and consumed by his quest to restore his honour, Lyram cannot help her find peace.

Together they journey into the desert to solve the riddle of their connection to each other, but their search leads into the middle of a killing field. Amidst the murdered souls, they balance on the cusp of understanding—what is the mysterious link between the Aharrises, the goddess Ahura, and the dragons?

But before they can complete the puzzle, the High Priestess attempts to bring a piece of an evil god into the world, and Ellaeva and Lyram are betrayed from all sides. If the Rahmyrrim cannot be halted, they will lose the most precious thing they have.

Ellaeva has always known her path ends at the ultimate sacrifice—but can an embittered priestess bring herself to fulfill her duty?
