Saint Thérèse of Lisieux, largely unknown when she died in a Carmelite convent at the age of twenty-four, became-through her posthumously published autobiography-one of the world's most influential religious figures. In Saint Thérèse of Lisieux Kathryn Harrison reveals the hopes and fears of the young girl behind the religious icon. Saint Thérèse of Lisieux shows us the pampered daughter of successful and deeply religious tradespeople who-through a personal appeal to the pope-entered a convent at the early age of fifteen. There, Thérèse embraced sacrifice and self-renunciation in a single-minded pursuit of the "nothingness" she felt would bring her closer to God. With feeling, Harrison shows us the sensitive four-year-old whose mother's death haunted her forever and contributed to the ascetic spirituality that strengthened her to embrace even the deadly throes of tuberculosis. Tellingly placed in the context of late-nineteenth-century French social and religious practices, this is a powerful story of a life lived with enormous passion and a searing, triumphant voyage of the spirit.
