    At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long-forgotten secrets of the past. That was why young Ross Murdock, above average in intelligence but a belligerently independent nonconformist, found himself on a "hush-hush" government project at a secret base in the Arctic. The very qualities that made him a menace in civilized society were valuable traits in a man who must successfully act the part of a merchant trader of the Beaker people during the Bronze Age.For once they were transferred by time machine to the remote Baltic region where the Russian post was located, Ross and his partner Ashe were swept into a fantastic action-filled adventure involving Russians, superstitious prehistoric men, and the aliens of a lost galactic civilization that demanded every ounce of courage the Americans possessed.Approx. 7 hours

    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.

    Like his current success Glory Lane, Foster's newest novel, an amazing dark contemporary fantasy, involves contemporary people who suddenly get involved in a life-or-death conflict in a fantastically changing world.

    It is a peaceful reign, held by compact and not by conquest. Again and again, when rebellion threatens the Terran Peace, the natives of the rebellious world have turned against their own people and sided with the men of Terra; not from fear, but from a sense of dedication. There has never been open war. The battle for these worlds is fought in the minds of a few men who stand between worlds; bound to one world by interest, loyalties and allegiance; bound to the other by love. Such a world is Wolf. Such a man was Race Cargill of the Terran Secret Service… At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory. But that had all seemingly ended. For six long years he'd sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud. But when The Door Through Space swung suddenly open, the feud was on again—and with it a plot designed to check and destroy the Terran Empire.
