Twenty Thousand Leagues Under the Sea is one of Jules Verne's most iconic and visionary novels. It follows the journey of Professor Pierre Aronnax, his servant Conseil, and Canadian harpooner Ned Land as they are taken aboard the mysterious submarine Nautilus, commanded by the enigmatic Captain Nemo. What begins as a mission to investigate a sea monster turns into a deep-sea odyssey through a world of underwater wonders, shipwrecks, lost civilizations, and the hidden forces of nature. With rich imagination and early science-fiction brilliance, Verne explores the limits of technology and the depths of the ocean long before submarines were a reality. The novel is not only an adventure tale but also a philosophical reflection on freedom, vengeance, and isolation beneath the waves. It remains a timeless classic that continues to inspire readers and creators around the world.
