Sister Helen Prejean's work as an activist nun, campaigning to educate Americans about the inhumanity of the death penalty, is known to millions worldwide. Less widely known is the evolution of her spiritual journey from one who prayed for God to solve the world's problems to one engaged full-tilt in the work to transform societal injustices. Sister Helen grew up in a well-off Baton Rouge family that still employed black servants. She joined the Sisters of St. Joseph at the age of eighteen and was in her forties when she had an awakening that her life's work was to immerse herself in the struggle of poor people, forced to live on the margins of society. In this honest and humorous account Sister Helen writes openly about her friendships with other women who have inspired and nurtured her. Her close friendship with a priest, fiercely intent on marrying her, challenged her vocation in "new territory of the heart." The final page of River of Fire ends with the opening page of Dead Man Walking, when she was first invited to write a man on Louisiana's death row. River of Fire is a book for anyone interested in journeys of faith and spirituality, doubt and belief, and "catching on fire" to purpose and passion. It is a book, written in accessible, luminous prose, about how to live a spiritual life that is wide awake to the sufferings and creative opportunities of our world.
