By Saint Louis de Montfort
This is probably the finest book ever written about the Rosary; it appeals to all ages. St. Louis de Montfort shows the great spiritual power of the Rosary and tells why the Rosary is the most important private prayer. Canon William says of De Montfort's book, "It goes far beyond mere research. We might say that it contains everything that can be said about the Rosary -- its content and form, its real worth, about the instruction necessary for its appreciation and use."
This is a wonderful little book for growing in your devotion to the Rosary!
This is also available as an audio book on CD.
