Based on several hundred letters exchanged between Robert Ellsberg and Sister Wendy on an almost daily basis during the last three years of Sister Wendy's life, the correspondence initially dealt with lives of saints, the meaning of holiness, and the spiritual life, but they soon expanded into a deep and intimate exchange that encompassed their whole lives, the subject of love, suffering, joy, and the presence of grace in everyday life. For Sister Wendy-by calling and temperament, a hermit-this involved an expansion of her spiritual and emotional horizons that prepared her for her final days.
