Everything changes for thirteen-year-old Aster the night her brother dies. Suddenly she's the only hope of the family, and instead of an early marriage to a boy from her small village in Pakistan, her parents decide to send her to the government high school in her brother's place. Aster is excited about this unexpected opportunity for a career, but, as a Christian, she is unprepared her for the difficulties of attending a Muslim school: her fellow students are far from welcoming and one of her teachers takes an instant dislike to her. One day, she is accused of intentionally making a spelling mistake to insult the holy prophet. Her teacher is incensed and accuses her of blasphemy. A violent crowd forms outside the school and Aster is taken to jail to be tried at a later date.
