Eleanor is born during a brilliant harvest moon. Moments after her birth, while she lies safely in her grandfather's arms, he tells her, "No matter where we are, we will always share the moon." And they do. As Eleanor grows, her grandpa teaches her to love the moon. Together they observe it in all its permutations as it waxes and wanes. Soon, Eleanor sees the moon in everything, and when she and her parents move away, these moon sightings give her comfort and make her feel like her grandfather is close by.
