In Underland, Robert Macfarlane delivers an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself. Traveling through the dizzying expanse of geologic time-from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come-Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind.
