In a future where every human becomes their own country, the world collapses into 8 billion isolated "nations of one." Borders no longer divide lands-they divide hearts. Connection becomes a crime. Empathy is labeled a threat. Trust disappears from the dictionary.What began as a dream of ultimate freedom slowly destroys the foundation of humanity itself.Twelve-year-old Mira Sael, born on the very last day before nations disappeared, grows up in a world where people no longer speak, share, or care. But when she discovers an old forgotten notebook titled "The Country of Us," she finds handwritten stories of a time when humans lived together, not apart. Inspired, Mira makes a decision no one has dared in decades: She will travel across continents, collect one million human stories, and remind the world of what it means to belong to one another.With nothing but her backpack and unbreakable belief in humanity, Mira crosses silent cities, abandoned airports, floating digital borders, and cold human walls-touching hearts one story at a time. Each story becomes a spark. Each spark becomes a movement.Her mission is impossible. Hope is extinct.But sometimes, it takes just one child to start a human revolution.This is the unforgettable, heart-touching journey of how a little girl rekindled the lost heartbeat of humankind-and united the world into a single global nation built not on land, power, or politics, but on love, empathy, and shared humanity.A deeply emotional, visionary, and uplifting novel for readers who loved The Alchemist, Wonder, and The Boy, The Mole, The Fox and The Horse.A soul-soothing reminder that the greatest passport we can carry is a compassionate heart.
