Twenty-three nuns live a cloistered life behind the walls of Santa Catalina Monastery in the heart of Arequipa, Peru. While the oldest active nun, Sister Consuelo de Jesus, has been a member of the cloister for 61 years and the youngest novice, Sister Heidi Marjorie, has lived with the order for a mere three months, both women have devoted their lives to God through service and prayer.
