Six-year-old Niko Karaam has never known a life outside civil war. He rarely leaves his parents' small apartment, and from its small balcony he listens to the world outside tumble down one building at a time. But after a car bomb kills his pregnant mother, Niko is thrust into a much wider and confusing world without apartments or balconies, as he and his father Antoine embark upon the open seas on an impossible international adventure in search of a new place to call home. Throughout a twelve-year odyssey that leads them across seven countries, young Niko will have to choose between his swollen faith in an increasingly God-like and unreliable Antoine, and the pragmatic, hard-nosed alternatives that will ultimately lead to a better future.
