As many saints have said - and St. Louis de Montfort demonstrates - Our Lady is the short and easy way to Our Lord. In Her we are molded to be like Christ. This book details the reasons for and the way to practice true devotion to Our Lady so that through Her we may attain eternal union with Him. One read is not enough; this is a spiritual work to read for a lifetime as it teaches a devotion to practice for a lifetime.
In addition to "True Devotion to Mary", this particular edition contains supplements to help the reader prepare for and make his total consecration to Jesus through Mary, pray the Little Crown, pray the Rosary according to St. Louis de Montfort's method, and learn about the Confraternity of Mary Queen of All Hearts. It's more than worth the price of admission.
