. . What then, my God, shall I do?" The Purple Cloud is widely hailed as a masterpiece of science fiction and one of the best "last man" novels ever written. A deadly purple vapor passes over the world and annihilates all living creatures except one man, Adam Jeffson. He embarks on an epic journey across a silent and devastated planet, an apocalyptic Robinson Crusoe putting together the semblance of a normal life from the flotsam and jetsam of his former existence. As he descends into madness over the years, he becomes increasingly aware that his survival was no accident and that his destiny—and the fate of the human race—are part of a profound, cosmological plan.

    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.

    The Peace Authority conquered the world with a weapon that never should have been a weapon--the "bobble," a spherical force-field impenetrable by any force known to mankind. Encasing governmental installations and military bases in bobbles, the Authority becomes virtually omnipotent. But they've never caught Paul Hoehler, the maverick who invented the technology, and who has been working quietly for decades to develop a way to defeat the Authority. With the help of an underground network of determined, independent scientists and a teenager who may be the apprentice genius he's needed for so long, he will shake the world, in the fast-paced hard-science thriller that garnered Vinge the first of his four Hugo nominations for best novel.
