To Become a Whale tells the story of 13-year-old Sam Keogh, whose mother has died. Sam has to learn how to live with his silent, hitherto absent father, who decides to make a man out of his son by taking him to work at Tangalooma, then the largest whaling station in the southern hemisphere. What follows is the story of a gentle boy trying to make sense of the terrible reality of whaling and the cruelty and alienation of his new world.
