Shortly before suffering a tragic car accident, Kate McConnell wrote the simple but powerful words of Psalm 23 on a piece of paper to give to her wayward and confused son. "The Lord is my shepherd; I shall not want. . . ." As she loses consciousness from her injuries, she wonders if she's done enough with her life. When a lonely dry-cleaning employee finds Kate's humble, handwritten copy of the psalm, it begins an incredible journey around the world, forever changing the lives of twelve very different people. From a soldier wounded in Iraq, to a young Kurdish girl fleeing with her family to Turkey, to a Kenyan runner about to begin the Rome Invitational Marathon, the power of the ancient words begins to take shape in various ways, drawing us into these stories inexplicably linked by the passing of the psalm from one recipient to the next. Eventually, Kate's paper makes it back to its starting place, and she discovers the unexpected ways that God moves and changes lives through even our smallest actions.
