Based on Robert Silverberg’s bestselling Sci-Fi novels about Humanity’s search for immortality out among the stars.

Ex-lieutenant Eddie Gundersen returns to Belzagor on a scientific expedition to the borders of the indigenous lands, where he must face his nemesis, Kurtz, and his own inner demons on a planet which still has hidden secrets. "COLONIES: Return to Belzagor" is a new edition of the previously released "Downward to the Earth" (2017). It has been edited for content.

Who knoweth the spirit of men that goeth upward, and the spirit of the beast that goeth downward to the earth? –Ecclesiastes 3:21 Okay, they did resemble elephants, it can't be denied. That led many people to underestimate the Nildoror and their obviously more fearsome commensals, the Sulidoror. But aliens should never be judged by human standards, as the Company learned to its cost when Holman's World, now once again known as Belzagor, was given back to the natives and the Company sent packing. Now Edmund Gunderson, once head of the Company's operation on this world, has come back across the galaxy to settle old scores with the Nildoror. If he can even get them to acknowledge his existence. Downward to the Earth is a classic from the golden age of Robert Silverberg's career in the 1970s. His homage to Joseph Conrad's Heart of Darkness, it remains as fresh and powerful today as the day it was written. Our Orb edition will have a map of Gunderson's journey across Belzagor and a new introduction by the author. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Earth 2381: The hordes of humanity have withdrawn into isolated 1000-story Urbmons, comfortably controlled multicity-buildings which perpetuate an open culture of free sex and unrestricted population growth. Nearly all of Earth's 75 billion live in the hundreds of monolithic structures scattered across the globe, with the exception of the small agricultural communes that supply the Urbmons with food. When a restless Urbmon computer engineer begins to think unblessworthy thoughts of making a trip outside, he risks being labeled a flippo, for whom there is only one punishment.

Robert Silverberg's debut novel, first published in 1955.
