Very informative and interesting!
Easy to read, small chapters make this book a great devotional guide for understanding the history and blessings of the Rosary. The book, having been written long before the Luminous Mysteries were introduced, mentions only the Joyful, Sorrowful and Glorious Mysteries, but the information is easily applied to the Luminous Mysteries as well.
As a convert to Catholicism I found this book very helpful in understanding the Rosary. I think it's also a great history of how the Rosary came to be and how it became so popular. Even "cradle" Catholics who love the Rosary, or just want a better understanding, would like this book.
This unlocks much about the Rosary that I never knew. I have a fuller experience now, after reading it, than ever before.
