Eleven-year-old Darcy Webster is hoping for a Christmas miracle to bring her father home from the war. Eleven-year-old Darcy hasn't lived in any one place long enough to have a best friend - until her family settles in Frenchtown and she meets Kathleen Mary O'Hara. Darcy is spellbound by Kathleen Mary's vivid tales of Catholicism. She shows Darcy a world beyond Frenchtown: a world of daring games and secrets, of sins and miracles. With Darcy's father off fighting the war somewhere in Europe, Kathleen Mary couldn't have come into her life at a better time. Then, just as suddenly as they appeared, Kathleen Mary and her family disappear. While Darcy waits to hear from her, she learns that her father is missing in action. Christmas is coming, and Darcy is unsure about the power of God's love. Will the miracle she hopes for really happen?
