Part of the Heroic Hearts Series by Charles Awanda, this beautiful book tells the story of Saint Juan Diego, the humble messenger of Our Lady of Guadalupe. Chosen by the Virgin Mary, Juan carried her message to the bishop and delivered a miraculous sign—roses in winter and her image on his cloak. With faith and simplicity, Juan helped bring hope to millions. His story reminds children that God uses even the humblest hearts for great missions.
