The Mysterious Island book summary
In March 1865, during the American Civil War, five prisoners escape from besieged Richmond in a balloon and are swept by a storm across the Pacific to an unknown island. The engineer Cyrus Harding, the reporter Gideon Spilett, the sailor Pencroft, young Herbert and Harding’s servant Neb, with the dog Top, name it Lincoln Island and make their home in a cave high in a granite cliff. With science and hard work they make fire, pottery, iron, glass and even a boat, and they tame an orangutan called Jup. Yet a lead bullet in a young peccary, a chest of tools and weapons washed ashore and other strange events convince them that someone unseen is watching over them. Jules Verne’s novel of 1874–1875 is a story of survival, ingenuity and teamwork, linked to his earlier In Search of the Castaways and Twenty Thousand Leagues Under the Sea.
