"An . . . exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself. From the birth of the universe to a post-human future, from the prehistoric art of Norwegian sea caves to the blue depths of the Greenland ice cap, from Bronze Age funeral chambers to the catacomb labyrinth below Paris, and from the underground fungal networks through which trees communicate to a deep-sunk 'hiding place' where nuclear waste will be stored for 100,000 years to come"--OCLC.
