They were the greatest trio of swashbuckling adventurers ever to ship out to the stars! There was giant Hal Samdu, rocklike Jay Kalam and the incomparably shrewd and knavish Giles Habibula. Here is their first thrilling adventure - the peril - packed attempt to rescue the most important person in the galaxy, keeper of the vital secret essential to humanity's survival in the deadly struggle against the incredibly evil Medusae... The Legion of Space is the first self-contained novel in Jack Williamson's epic Legion of Space series, an all-time classic of adventurous science fiction to rank with 'Doc' Smith's Lensman saga and Isaac Asimov's Foundation trilogy.

This new collection of works by a master of science fiction adventure includes two complete novels--"Planet Run," on which he collaborated with Gordon R. Dickson, and "A Trace of Memory." Original.

"I am omnipotent and omniscient. I want every man on every planet to shudder and grow pale when he thinks of Me. For I have suffered gross injuries that must be avenged..." This sinister message - and a loathsome serpent-like trademark - were the only clues the Legion of Space had to the identity of Mankind's most evasive and horrible enemy. But meanwhile, He or IT - had meticulously begun to destroy the world... The Legion of Space was well accustomed to facing mortal peril in the black depths of outer space in order to defend humanity against its unearthly foes. But even they were to find their courage and ingenuity tested to the utmost limits in their fight against the vile phantom that called itself God and shrouded the Universe in an incredible web of terror...

The fourth novel in the classic Legion of Space series. In swarming hordes they poured forth from the core of the Nebula: the shadowflashers - nightmarish parasites bent on enslaving the minds and bodies of the entire human race. Already they had killed the Keeper of the Peace, and stolen the great secret weapon Akka. Now nothing stood between Mankind and the ultimate destruction... It was Jil Gyrel who first sensed danger. Daughter of a lost Legion pilot, Jil had inherited her father's uncanny gifts of navigation - and his courage. But what was one girl's bravery against the most monstrous evil ever to emerge from the treacherous oceans of space?
