Shade Over the Past: An Alien Intervention in Human Evolution (Paperback)

Shade Over the Past reflects a new approach to the science fiction genre. A group of superior beings, old lifeforms made of highly organized conglomerates of elementary particles, energy and sequences of information, come to Earth almost two million years ago and discover tribes of early hominids. The aliens sacrifice part of their almost unlimited power to live on Earth and guide these early humans on their dangerous journey through evolution. But not all of our ancestors are ready to be helped.
