The limits of fifteen-year-old Kambili's world are defined by the high walls of her family estate and the dictates of her fanatically religious father. Her life is regulated by schedules: prayer, sleep, study, prayer. When Nigeria is shaken by a military coup, Kambili's father, involved mysteriously in the political crisis, sends her to live with her aunt. In this house, noisy and full of laughter, she discovers life and love - and a terrible, bruising secret deep within her family.
