This is the story of two siblings, Samuel and Theodora. On his twelfth birthday, Samuel disappears, leaving it to Theodora to fit the pieces together. If the past had been different, then perhaps Samuel would not have disappeared. But the circumstances of his birth, the holiday when he was a baby, the tragic past of his beloved grandfather Elias, and even his own name, all lead to a vanishing, a dramatic rescue, and a perfect discovery.
