Kella Mabaki, dragon slayer extraordinaire, devoted sister, and celebrity hero of Jeenobi, has become a nobody by choice. Unable to continue hunting the dragons still tormenting her people and distanced from a brother she no longer understands, Kella is adrift in the city that was once her home. When she's captivated by a rumor that could mean the end to the dragon sickness plaguing her land, she becomes obsessed with learning the truth of it. Nobody or not, she's never been one for standing still.

Despite her beloved cousin's disappearance and her growing doubts toward the empire she serves, Litz is experiencing an unexpected period of stability in her life. Kella's arrival and the brewing war between their nations forces Litz to make a choice. Her country, career, and family, or the chance of making a better world with the woman she hasn't been able to forget?
