Every Sunday when she’s home from boarding school, brilliant and deeply religious 17-year-old Ainiara and her extended family gather for lunch at the home of her paternal grandmother. One day, she shocks everyone by revealing that, rather than pursue university, she is considering following her faith to become a cloistered nun.
