The Life of Saint Margaret Mary Alacoque by Rt. Rev. Emile Bougaud
This is considered to be the best biography of The Saint of the Sacred Heart Devotion. The whole story of the revelations, plus the definitive story of her life. Portrays St. Margaret Mary as a redoubtable soul, ready to give all for Jesus. And what an example she is! It is largely due to St. Margaret Mary that we know what we do about the Sacred Heart of Jesus.
