A restless young man defies his family's wishes to go to sea, faces capture and escape, and is later shipwrecked on a deserted island where he survives by building shelter, cultivating food, domesticating animals, and salvaging supplies. Years of solitude test his faith and ingenuity while he records his efforts to create a stable life. He discovers evidence of other people, rescues and educates a native companion, and together they ward off hostile groups and reclaim a vessel. The narrative follows practical survival, moral reflection, and the uneasy cross-cultural encounter that leads to his eventual return home.
