In sixteen-year-old Felicita's world, magic is strictly controlled - or so those in power like to believe. After her dearest friend, Ilven, kills herself to escape an arranged marriage, Felicita chooses freedom over privilege. She fakes her own death and leaves her sheltered life as one of Pelimburg's magical elite behind. Living in the slums, scrubbing dishes for a living, she falls for charismatic Dash while also becoming fascinated with vampire Jannik. Then something shocking washes up on the beach: Ilven's death has called out of the sea a dangerous, wild magic. Felicita must decide whether her loyalties lie with the family she abandoned, or with those who would twist this dark power to destory Pelimburg's caste system, and the whole city along with it.
