The pilgrims of the Raven and the Dove make their way to the Holy Island of Iona, the ancient heart of Celtic Christianity in Britain. There, they walk the grounds where St. Columba built his monastery on the edge of the world, and tell the story of the Irish prince whose pride cost three thousand lives -- and whose repentance built a church that would illumine the north for generations. “The Raven and the Dove” is a pilgrimage tale spanning Scotland and Northumbria, told by four friends who went in search of the holy people and places on the northern border between the Celtic and the English.
