Jules Verne 
Journey to the Center of the Earth [EPUB ebook] 

What a stunning discovery: an old, coded note that actually contains directions for reaching the Earth’s very core! And once he finds it, renowned geologist Professor Liedenbrock can’t resist setting out with his 16-year-old nephew to go where only one man has gone before. Jules Verne takes young readers on one of the most incredible journeys ever imagined, from Iceland’s frozen tundra far down into fantastic underground prehistoric worlds and back up again through the fires of an erupting volcano.
