This book tells the story of Laura Vicuña (1891-1904). She was born in Chile, South America, but lived most of her life in Argentina. Her father died when she was three and she and her sister were left in the charge of her mother, until at the age of eight she joined the school run by the Salesian Sisters of St. John Bosco. Her short life serves as an inspiration and role model for Catholics, both children and adults. Her devotion to the Blessed Sacrament, Sacred Heart, and Blessed Virgin Mary, and her frequent Communion, as well as her great fervor in charity and obedience prove to everyone that it is possible to stay away not only from mortal sin but also from deliberate venial sin. Finally, in order to save from the fires of Hell the person most dear to her, her own mother, she offered herself a victim soul. She died at the age of 12 as a victim of domestic violence, and is still loved and admired by Catholics worldwide. The book also contains an examination of conscience for children.
