Out of Time's Abyss

On Caprona, the Land that Time Forgot, all of the world''s savage past still lived. Here were dinosaurs and flying reptiles, here were the most primitive of cavemen, and the last of the Bronze Age barbarians. But there was one more secret that the claws and fangs and sharp-edged spears guarded most of all.

This is the story of the man who tried to find that final secret. When Bradley, the adventurer, dared to cross the last terrible barrier to the heart of Caprona, he entered a world of wonder, terror, and danger beyond the imagination of any man—except Edgar Rice Burroughs.
