In 1917, Our Lady at Fatima asked for reparation and devotion to her Immaculate Heart, promising, "In the end, my Immaculate Heart will triumph. ... a period of peace will be granted to the world." But why does her Immaculate Heart matter so much? What's the connection between an immaculate heart and peace? And what does all this have to do with us average Catholics in the pews?

Taking its bearings from the beginning and end of salvation history, this booklet answers those questions. Following Our Lady's Immaculate Heart as our North Star, we'll learn what's needed for us to have immaculate hearts like the Mother of the Church and discover a pondering spirituality leading us on to become salt, light, and true offspring of the Mother of God.
