A French-language religious and spiritual work addressing the theme of victory over evil forces. The title suggests a practical or devotional treatment of spiritual conflict, framed within a Christian or faith-based understanding of moral and supernatural struggle. The available bibliographic record identifies a single paperback edition published by Bussière in 1990, but no description, subject headings, or genre data are provided with the record. As cataloged here, the work is best understood as a concise spiritual nonfiction title concerned with overcoming hostile or malign powers through religious belief, prayer, or spiritual discipline. Further review of the text would be useful to confirm its theological perspective and intended audience.
