This is the book the devil could not burn. A manuscript attacked, scorched, snatched away… and returned intact. What was meant to be destroyed became one of the most intense spiritual testimonies in Christian history. You are entering the heart of one of the most radical souls of the nineteenth century: Saint Gemma Galgani. This volume brings together three pillars of her interior life: Diary Autobiography Book of Ecstasies Presented together and complete in English for the first time. Gemma wrote out of obedience. Her spiritual director, Venerable Father Germanus, ordered her to set down in writing what she was living: visions, struggles, temptations, dialogues with Christ, with the Blessed Virgin, with her guardian angel… and direct confrontations with the devil. In the Diary, the invisible world becomes concrete: physical attacks from the enemy, conversations with her angel, corrections, falls, and constant rising again. Here, a true spiritual war is documented. In the Autobiography, Gemma lays bare her interior life. She sees herself as small, miserable, incapable… and at the same time completely loved by God. Her awareness of sin and her desire for holiness reach an intensity difficult to grasp through a modern mindset. In the Book of Ecstasies, we witness something even more bewildering: dialogues in a mystical state in which Gemma intercedes for sinners, argues with Jesus, offers herself as a victim, and actively participates in the redemption of souls. This book is a direct window into Passionist spirituality: Love for the Crucified Reparation for the sins of the world Union with the Passion of Christ Lucca, Italy, late nineteenth century. A sick young woman, without means, without a convent, without recognition. And yet, her soul reaches mystical heights that the Church would ultimately confirm: she was canonized in 1940. Holiness is combat. And true love is tested on the cross. Whoever enters these pages enters a room in Lucca… and a spiritual battle that remains alive today.
