Out of Time's Abyss

Out of Time's Abyss is a science fiction classic written by Edgar Rice Burroughs and first published in 1918. In Caprona, the land that time forgot, creatures from the world's savage past live on...dinosaurs, cavemen, and the last remnants of Bronze Age barbarians. But the claws and fangs and sharp-edged spears guard a terrible secret. Out of Time's Abyss is the story of a man who dares to uncover that secret. Crossing the last terrible barrier to the heart of Caprona, he enters a world of wonder, terror, and danger beyond imagining.
