What's with the Virgin Mary and the Number "13"?

Numbers are fascinating especially when their hidden meaning is brought to light. Biblical numerology leads to the symbolic typology of the number twelve with the twelve tribes, twelve apostles. Then there is the repetitious number seven in the Book of Revelation and of course, the 3 for the Holy Trinity. So what's with the number 13 and the Virgin Mary? Why is that number so seemingly important or meaningful in her history of apparitions and possibly in her life? Join the author in a mystery story that digs deeply into Our Lady's various apparitions, the history of the Rosary, Scapular and a curious star on the bottom of Our Lady of Fatima's dress. The reader will be surprised by all the thirteens in the book... certainly more than you might imagine.
