Sixteen-year-old Whisper, who has a cleft palate, lives in an encampment with three other young rejects and their caregiver, Nathanael. They are outcasts from a society (in the not-too-distant future) that kills or abandons anyone with a physical or mental disability. Whisper's mother visits once a year. When she dies, she leaves Whisper a violin, which Nathanael teaches her to play. Whisper's father comes to claim her, and she becomes his house slave, her disfigurement hidden by a black veil. But when she proves rebellious, she is taken to the city to live with other rejects at a house called Purgatory Palace, where she has to make difficult decisions for herself and for her vulnerable friends.
