In 2004, Danielle and her high-spirited, bohemian, very sage grandfather, "Papa," are planning a once-in-a-lifetime trip to Italy when a dramatic medical diagnosis makes the quest to get there urgent. A mysterious box of 1937 photos and letters shows up, and the original plan turns into an epic adventure they never could have imagined. With a rucksack full of playfulness, courage, and luminous pearls of Papa's wisdom, the duo time-travel across this true story, from 1937 through 2008: Visiting the magical splendor of eternal Italy; Experiencing the trials and triumphs of a Depression-Era New York; Defying tradition in mid-century Connecticut; and navigating unfamiliar, stormy waters in modern-day Florida. Once aboard, you'll realize you're not merely an observer of the journey, and not just a passenger on the caravan. You are a mighty companion on an inspiring, vibrant pilgrimage that helps explain infinity, compels the importance of listening to and telling other people's stories, and conveys the unending presence and power of unconditional love. Together you reach your destinations, and along the way discover the meaning of life, the truth about love, and the possibility that it all just might be one and the same.
