The classic science fiction novel, now back in print Clay is a man from the 20th Century who is somehow caught up in a time-flux and transported into a distant future. The earth and the life on it have changed beyond recognition. Even the human race has evolved into many different forms, now coexisting on the planet. The seemingly omnipotent Skimmers, the tyrannosaur-like Eaters, the sedentary Awaiters, the squid-like Breathers, the Interceders, the Destroyers—all of these are "Sons of Man". Befriended and besexed by the Skimmers, Clay goes on a journey which takes him around the future earth and into the depths of his own soul. He is human, but what does that mean?

How far will four friends go for immortality? This novel is Hugo and Nebula Award–winning author “Robert Silverberg at his very best” (George R. R. Martin). After Eli, a scholarly college student, finds and translates an ancient manuscript called The Book of Skulls, he and his friends embark on a cross-country trip to Arizona in search of a legendary monastery where they hope to find the secret of immortality. On the journey with Eli, there’s Timothy, an upper-class WASP with a trust fund and a solid sense of entitlement; Ned, a cynical poet and alienated gay man; and Oliver, a Kansas farm boy who escaped his rural origins and now wants to escape death. If they can find the House of Skulls where immortal monks allegedly reside, they’ll undergo a rigorous initiation. But do those eight grinning skulls mean the joke will be on them? For a sacrifice will be required. Two must die so that two may live forever . . . Stretching the boundary between science fiction and horror, Robert Silverberg masterfully probes deeper existential questions of morality, brotherhood, and self-determined destiny in what Harlan Ellison refers to as “one of my favorite nightmare novels.” This ebook features an illustrated biography of Robert Silverberg including rare images from the author’s personal collection.

'The explosion was painfully bright against the dark backdrop of the moonless New Mexico sky. To those who looked up at that precise moment - and there were many who happened to look up - it was as though a new star had momentarily blossomed in blue-white incandescence.' Only three human beings would ever know that the blinding flash in the sky on that night in 1982 was an exploding flying saucer. Only they would learn the truth about THOSE WHO WATCH - about the alien observers who came into this world in a crash landing from the stars. THOSE WHO WATCH is the strange, seductive story of three accidental colonists from outer space whose chance encounter with Earth brought revelation to three earthly counterparts - and triggered interplanetary conflict. It is a remarkable story by one of science fiction's most remarkable writers.
