Earth (Signet classics)
by Jules Verne
Category: Fantasy fiction

An adventurous geology professor mounts an expedition that descends into a subterranean world of luminous rocks, antediluvian forests, and fantastic marine life -- a living past that holds the secrets to the origins of human existence. Jules Verne's 19th-century action classic has the added appeal of a psychological quest, in which the journey is as significant as the destination.
