Sixteen-year-old Brieze is the apprentice and adopted daughter of a powerful wizard. She never met her biological father, a merchantman from the faraway Eastern Kingdoms who had a brief romance with her mother, then disappeared. When Brieze discovers her mother is still secretly, crazily in love with this man, even after seventeen years, she decides to find him, confront him, and get some answers from him for her mother's sake. In her small airship the Devious, she makes the long and dangerous journey to the Eastern Kingdoms. Along the way, she confronts pirates and the nocturnal ship-crushing beast known as the Nagmor. She survives a harrowing trip through the legendary Wind's Teeth. She discovers why her father disappeared, and in the process she learns the true version of her own story. When Brieze's boyfriend, Tak, receives word she's in danger, he sets out on his own journey east to help her. Will he be able to rescue her, or will she end up having to rescue him?
