The story in one page
When a ship founders, a Swiss father, mother, and their four sons find themselves stranded on a fertile, uncharted island. With only the supplies salvaged from the wreck and their own ingenuity, the family establishes a series of progressively elaborate residences — including an aërial castle in a giant tree — while cataloging local flora and fauna. As the boys grow into young men, they master the rugged landscape and transform their wilderness into a thriving, self-sustaining domain. Years later, an English ship appears, forcing a wrenching choice between returning to civilized Europe or remaining in the world they built themselves.
