This Catholic juvenile in the Vision Books series will appeal mainly to girls. Based on authentic sources, it recounts the life -story of St. Margaret Mary Alacoque, the 17th-century Visitation nun responsible for the modern devotion to the Sacred Heart. Her mystical way of life, visionary experiences, trials and persecutions at home and in the convent are imaginatively re-created here in a simple, interesting and inspiring manner. No false idealism about convent life mars the narration. Adults could read the volume comfortably and with profit.
