Rin is a student at the military academy of Synegard and the last of the people who mastered fire. After the island of Mugен was destroyed by Rin’s hands, the Federation’s invasion failed—but the war isn’t over, because the main enemy, Empress Dаzy, hasn’t been defeated yet. Rin hungers for revenge for Altan’s death, and with a detachment of shamans-цикe hunts the head of the Serpent. But they end up drawn into a political game between the empire and the governor of the Dragon province. And what is Rin worth without the cruel god Phoenix’s power? Are her allies’ intentions truly pure?
