Edgar Rice Burroughs 4 hr 53 min read

When David Innes, Emperor of Pellucidar, is imprisoned in a Korsar dungeon, Jason Gridley speeds to Africa to enlist the one man who can brave the inner world's terrors, Tarzan of the Apes.

Edgar Rice Burroughs's 1929 novel is a rousing crossover of his Tarzan and Pellucidar series. Vivid, thrilling, gloriously imaginative. Read it for the ape-man voyaging by dirigible to the Earth's core, prehistoric beasts, a hollow-world sun, and two of ERB's greatest creations in one grand adventure.
