Out of Time’s Abyss: The Caspak Series, Book 3 Audiobook (Free)

On Caprona, the Land that point Forgot, every one of the world’s savage former still lived. Here were dinosaurs and traveling reptiles, here were probably the most primitive of cavemen, and the last of the Bronze Age group barbarians. But there is one more key the fact that claws and fangs and sharp-edged spears guarded most of all.

This is actually the story of the person who tried to find that final secret. When Bradley, the adventurer, dared to combination the final terrible barrier to the center of Caprona, he moved into a world of wonder, terror, and risk beyond the creativity of any man-except Edgar Grain Burroughs.
