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. Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.
