Classics, modern fiction, non-fiction and more. Written for secondary and adult students the Oxford Bookworms Library has seven reading levels from A1-C1 of the CEFR. When men find gold in the frozen north of Canada, they need dogs - big, strong dogs to pull the sledges on the long journeys to and from the gold mines. Buck is stolen from his home in the south and sold as a sledge-dog. He has to learn a new way of life - how to work in harness, how to stay alive in the ice and the snow... and how to fight. Because when a dog falls down in a fight, he never gets up again. CEFR B1 Word count 10,965
