20000 Leagues Under the Sea

Twenty Thousand Leagues Under the Seas is a classic science fiction novel by French writer Jules Verne published in 1870. It tells the story of Captain Nemo and his submarine Nautilus as seen from the perspective of Professor Pierre Aronnax.
As the story begins in 1866, a mysterious sea monster, theorized by some to be a giant narwhal, is sighted by ships of several nations; an ocean liner is also damaged by the creature. The United States government finally assembles an expedition in New York City to track down and destroy the menace. Professor Pierre Aronnax, a noted French marine biologist and narrator of the story, who happens to be in New York at the time and is a recognized expert in his field, is issued a last-minute invitation to join the expedition, and he accepts. Canadian master harpoonist Ned Land and Aronnax's faithful assistant Conseil are also brought on board.
