In this easy-to-read introduction to the wondrous power of the holy Rosary, internationally acclaimed Mariologist and speaker Fr. Donald Calloway, MIC, shares some of the greatest triumphs and miracles attributed to Our Lady's favorite devotion. Journey with Fr. Calloway from the forests of France, where St. Dominic was first given the Rosary, to the seas where the Battle of Lepanto was fought; from the battlefield of the hearts of lapsed Catholics like Bartolo Longo to the minds of Albigensian heretics. With a foreword by Bishop Athanasius Schneider, this little book will inspire you to take up and spread this most powerful devotion.
