Just before dawn on Saturday the 9th of December, 1531, Juan Diego was on his way to Mass near Mexico City. He came to a hill known as Tepeyac just as day broke. He could hear the singing of many beautiful birds, but then the singing suddenly stopped. As he looked towards the top of the hill he heard someone calling his name. He was amazed to see a beautiful lady. Her clothes glimmered like the sun and her brilliance made the rocks and plants sparkle like jewels. Juan Diego bowed deeply before her, as she told him that she was Holy Mary, the Mother of God. Then she instructed him to go to the bishop in Mexico City and ask him to build a great church so that people would come to know her love, compassion, and protection. But the bishop wished for a sign. In this beautiful retelling of the story by award-winning author, Demi, find out how the miracles performed by the Virgin of Guadalupe persuaded the bishop to build the church; how they caused ten million Aztecs to convert to Catholicism within just eight years; and why the basilica dedicated to the Virgin of Guadalupe today receives 20 million pilgrims per year, making it the most popular Christian pilgrimage site in the world.
