It is a tremendous presence towering over the world—Kosa Saag, the Wall—a monstrous assemblage of cliffs, ravines, and mountains. At its Summit, on the highest peak of all, far above the clouds, live the gods themselves. Each year, from the village of Jespodar at the foot of the imposing Wall, twenty men and twenty women, selected and trained at arduous length, set forth on a Pilgrimage. Against overwhelming odds they will attempt to scale the Summit, meet with the gods, and gain new knowledge. A few Pilgrims will return as madmen. Most will never be seen again. For Poilar Crookleg, the Pilgrimage has been a lifelong dream. Years ago he and his childhood friend Traiben vowed that they would one day make the Pilgrimage together, converse with the gods, and return not as madmen but as teachers of wisdom. Now it is their year of selection, and the two young men set forth among the chosen forty, determined to succeed where so many before them have failed. Along the way, they must brave ghosts and ravenous Wall-hawks, traverse terrifying Kingdoms and blasted landscapes of heat and ice, and then face the greatest challenge of all…the temptation of eternal life in a paradise of pleasure. At the end, for the few who endure, lies the Summit itself, and with it the secret of the gods—a secret so strange and unsettling that it will shatter centuries of belief and change the world forever. In Kingdoms of the Wall, Robert Silverberg has crafted a masterpiece of the first order, an adventure filled with awesome mystery and disturbing revelation, a voyage to the heart of creation itself as the inhabitants of an alien world strive to learn the truth about themselves and their gods, a truth as harsh and unforgiving as the forbidding heights of Kosa Saag.

It had been five hundred years since the distant Terran Colony of Corwin had communicated with Earth. But now Corwin was threatened by the indomitable warriors of Klodni and the peaceful planet desperately needed help. Baird Ewing was the ambassador chosen by his people to find that help and save Corwin from destruction. But Earth had changed . . . Ewing found a decadent world of worthless pleasure-seekers devoid of hope and incapable of help. The only remaining vestige of the old world on Earth was to be found in the College of Abstract Science. It was Ewing's last hope. If he failed it was the end of the line for him, Corwin - and the galaxy. First published in 1958.

From the man who has won more Hugo and Nebula Awards than any other author in the history of fantastic literature, three complete novels that embody the concept of time travel. LETTERS FROM ATLANTIS Time travel has allowed Roy's consciousness to enter the mind of the heir to Atlantis's throne. But if he was in an Atlantis unlike anything the researchers had predicted, then what were its secrets? And when would it be destroyed? PROJECT PENDULUM The nature of time mechanics requires that the two travellers' masses be precisely matched; for that reason, the first time travellers must be a pair of identical twins. What neither planned on, however, was how the inhabitants of those times would react to their presence.... THE TIME HOPPERS In the 25th century, the only escape from suffocation in a totally controlled environment is to 'hop' backward through time. However, since time-hopping is outlawed, it must be stopped - but not too quickly. For the history of the 1970s includes the arrival of hoppers who have not yet left the 2490s!

I wrote this one in October, 1987 for an anthology I was editing myself, the basic idea of which involved using computer-generated simulacra of actual historical figures set in conflict against one another. The ones I chose were Socrates and Francisco Pizarro, and the story very quickly became an exciting thing to write as these two powerful personalities began to clash. I think it’s one of the major achievements of my career.It was published in ASIMOV’S SCIENCE FICTION and then in TIME GATE, my anthology, and it was picked for Gardner Dozois’ 1989 YEAR’S BEST SCIENCE FICTION anthology. And at the World Science Fiction Convention in Holland in August, 1990, it brought me the Hugo award for Best Novelet.

Science fiction legend Robert Silverberg reflects on some of his earliest, least-reprinted tales in this new Planet Stories collection Between 1956 and 1958, Silverberg contributed dozens of short stories and novellas to the digest pulps, each written in the bombastic, high-adventure style of the original Planet Stories magazine. Since then, those tales have re-appeared only rarely (and sometimes never again) in long out-of-print paperback anthologies. This volume, the first of three to come this year, features seven hard-to-find classic Silverberg novellas: Slaves of the Star Giants, Spawn of the Deadly Sea, The Flame and the Hammer, Valley Beyond Time, Hunt the Space-Witch , The Silent Invaders, and Spacerogue.
