At the Earth's Core

by Edgar Rice Burroughs

What if the Earth isn’t solid—but hollow? And what if an entire hidden world exists beneath our feet? In At the Earth's Core, legendary author Edgar Rice Burroughs introduces Pellucidar, a vast, prehistoric land buried deep within the Earth’s interior. When adventurer David Innes and inventor Abner Perry test a powerful new drilling machine, they find themselves trapped in a subterranean world where time stands still, strange creatures roam, and an ancient civilization thrives. A lost world untouched by time, ruled by reptilian overlords. A journey through the unknown, filled with danger, mystery, and adventure. A thrilling blend of science fiction, fantasy, and exploration, At the Earth's Core remains a cornerstone of hollow earth mythology and speculative fiction—inspiring later theories about what might lie beneath the polar regions.
