Michael Storm has stumbled upon a strange new world. Deep in the mountains of Peru, he crosses a gateway leading to a world of mutated monsters, tribal apemen, and wondrous futuristic technology. The key to Storm's survival in this bizarre new reality is his very identity - is he the godlike warrior Thundar, spoken of in the prophecies, or merely a man in the wrong place at the wrong time? A tale of myth and adventure in the tradition of Edgar Rice Burroughs. With a new introduction by the author describing his experiences in Peru after World War II and how his search for lost Incan treasure helped inspire this book.
