In this luminous spiritual classic, Fr. Henri-Marie Boudon, one of the Church's most gifted spiritual teachers, draws back the veil on the world of the angels. With clarity, reverence, and profound insight, he reveals why devotion to the angels is not optional ornamentation in the spiritual life but a vital source of strength, protection, and peace.

Boudon shows how the angels accompany us at every moment, encouraging virtue, restraining evil, and leading us ever closer to God. Through rich metaphors, Scripture, and the wisdom of the saints, he awakens gratitude and love for these heavenly guardians who labor ceaselessly for our salvation.
