From Fr. Michael E. Gaitley, MIC, comes an extraordinary 33-day journey to Marian consecration with four giants of Marian spirituality: St. Louis de Montfort, St. Maximilian Kolbe, Blessed Mother Teresa of Calcutta, and Blessed Pope John Paul II. Father Michael masterfully summarizes their teaching, weaving their thoughts into a user-friendly, do-it-yourself retreat that will bless even the busiest of people.
