Twenty Thousand Leagues Under The Sea (Illustrated) [EPUB ebook] 

Sent to investigate mysterious encounters that are disrupting international shipping, Professor Aronnax, his servant Conseil, and disgruntled harpooner Ned Land are captured when their frigate is sunk during an encounter with the ‘monster.’ The submarine Nautilus and its eccentric Captain Nemo afford the professor and his companions endless fascination and danger as they’re swept along on a yearlong undersea voyage.
