15-year-old Hannah Roberts remembers when her father was her closest friend. The image is hazy, though, pulled from her distant childhood memories, and her father is now very cold and distant. Her mother is not much better. Feeling orphaned, Hannah lives a lonely life with her wealthy, ailing grandmother. As Christmas nears, Hannah learns a shocking truth: the man she believed was her father is not her parent after all. In an effort to find answers, she begins a desperate search for her real father, Air Force pilot Mike Conner. A local politician and a newspaper catch wind of her quest, a national TV station posts a letter from her, and soon everyone is caught up in Hannah's hope--that she'll find her father before the holidays.
