Edgar Rice Burroughs 3 hr 29 min read

At the Earth's core lies Pellucidar, a savage inner world of dinosaurs and cavemen lit by an eternal sun, and David Innes returns to it to build an empire and win back his lost love.

Edgar Rice Burroughs's 1915 novel, second in the Pellucidar series, is a rousing hollow-earth adventure. Colorful, breathless, imaginative. Read it for classic Burroughs, a wild romp through a prehistoric world beneath our feet, all peril, romance, and derring-do.
