Search Worlds Without End

Hugo, Nebula and Locus award winning novella. It originally appeared in Isaac Asimov's Science Fiction Magazine, September 1979. At least three different versions of the novella have been published. It can be found in the anthologies The Best Science Fiction Novellas of the Year #2 (1980) edited by Terry Carr, Nebula Winners Fifteen (1981), edited by Frank Herbert, Baker's Dozen: 13 Short Science Fiction Novels (1985) edited by Isaac Asimov, Martin H. Greenberg and Charles G. Waugh, and The Hugo Winners, Volume 5: (1980-82) (1986), edited by Isaac Asimov. It is half of Tor Double #6: Enemy Mine/Another Orphan (1989, with John Kessel) and is included in the collection Manifest Destiny (1980).

The story was made into the movie Enemy Mine directed by Wolfgang Petersen and starring Dennis Quaid and Louis Gossett, Jr. in 1985. The movie in turn was the basis van the novelization Enemy Mine (1985), written in collaboration with David Gerrold.

First came the news that a flying saucer had landed in Iowa. Then came the announcement that the whole thing was a hoax. End of story. Case closed.

Except that two agents of the most secret intelligence agency in the U.S. government were on the scene and disappeared without reporting in. And four more agents who were sent in also disappeared. So the head of the agency and his two top agents went in and managed to get out with their discovery: an invasion is underway by slug-like aliens who can touch a human and completely control his or her mind. What the humans know, they know. What the slugs want, no matter what, the human will do. And most of Iowa is already under their control.

Sam Cavanaugh was one of the agents who discovered the truth. Unfortunately, that was just before he was taken over by one of the aliens and began working for the invaders, with no will of his own. And he has just learned that a high official in the Treasury Department is now under control of the aliens. Since the Treasury Department includes the Secret Service, which safeguards the President of the United States, control of the entire nation is near at hand . . .

The Gurus came in peace, bearing gifts.

They were a highly advanced, interstellar species who brought amazingly useful and sophisticated technology to the human race. There was, of course, a catch. The Gurus warned of a far more malevolent life form, beings who have hounded the Gurus from sun to sun, planet to planet, across the cosmos. Pundits have taken to calling them the Antagonists - or Antags - and they have already established a beachhead on Mars. In exchange for all they've done for us, the Gurus would now like our help.

Enter Master Sergeant Michael Venn, a veteran Skyrine (a Marine who is specially trained for off-world combat) who is dropped onto the Red Planet with his band of brothers on a mission to take down as many Antags as possible.

But from the moment they're dropped through the thin Martian atmosphere, their mission goes horribly, terribly wrong. From a group of female special ops Skyrines with secret orders, to mysterious humans who've settled on Mars, to the overwhelming and highly-reinforced Antags themselves, Venn and his brothers will face impossible odds just to survive - let alone make it home alive.
