Abner Harris was sent to Earth on a mission of extreme urgency. The universe was in danger of enslavement by the Medlins, and the fight against them called for Harris to assume the disguise of a flesh-and-blood Earthman.

But he discovered that the real villains of space were not the Medlins or the people of Earth: they were his own kind.

Suddenly he was alone, alienated from his own race, hated by the Medlins, and an imposter on Earth. No matter what side he chose he’d be a traitor.

Yet choose he must – or remain for ever a man without a planet.

How do you justify genocide?

Kennedy had a job to do. It was as simple as that. He was paid to do a job, and he did it.

His job was to convince the Earth’s population that a hapless race of sapient creatures living peacefully on a distant planet must be destroyed as a menace to the Earth.

On a future Earth, where invading aliens have forced humanity to revert to a feudal society and conducting scientific research is punishable by death, it’s good to be the heir to a duchy. Unless your brother has been burnt as punishment for heresy. And unless you intended to do something about it . . .

The alien ruins that dotted Earth’s landscape were an enigma.

Archaeologist Rond Heshke dismissed as a ridiculous hoax the photographic evidence which suggested that the ruins disobeyed the laws of time. The Titanium Legions believed that the ruins had been left behind by an invading force from space, which had been repelled in a past age and whose imminent return was feared.

It was not until the Titanium scientists perfected their time machines that the truth began to emerge piece by piece: that the builders of the ruins belonged not to the stars but to Earth’s own future, and that the dreaded confrontation was indeed shortly due – not with aliens, but in a form more horrifying, more calamitous, than anything imaginable…

For Earth was to be the victim of an extraordinary cosmic accident. Time itself was about to collide! Mankind’s leaders became even more fanatical, pressing on with new plans, determined at all costs to survive…

The alien spaceship was unthinkably huge, enormously powerful, apparently irresistible. It came from the void and settle on Earth, striking awe into the hearts of all who saw it. Its burden, however, was not conquest – but a call for the brilliant team of scientists, Arcot, Wade and Morey, explorers of the islands of space. And what they learned was an offer of an alliance against an invading foe so powerful that no known force could turn back.

John W. Campbell’s Invaders from the Infinite is a veritable odyssey of the universe, exploring world after world, and uncovering cosmic secret after cosmic secret. Here is a classic novel of super-science that may never be surpassed.

They had conquered Mars! Earth was next.

And in the council chambers at Washington, Earth’s leaders gathered to face the peril.

Mars had gone down to defeat in one hour and thirty-four minutes. And now a fleet of creatures from outer space was headed towards Earth.

All eyes turned to Eldin Raigmore, President of the United States – the one man to be trusted above all others. One by one the elite were dispatched on missions of last-minute strategy. They went with confidence, inspired by the swift, sure mind of Raigmore.

Civilization rested in his hands. And he was a secret member of the invader race!

After Richard Garrison lost his sight in a terrorist explosion, he developed vast mental powers that more than compensated for his blindness. He mastered the Psychomech machine, then used it to conquer his enemies and restore his dead love to full and vibrant life. Psychomech also revealed to Garrison the Psychosphere, a startling reality where mental powers reigned supreme and could influence people and events on Earth.

Once he was nearly godlike – or demonic, if one dared become his enemy – but now Garrison’s mental abilities grow weaker with each use. He tries desperately to conserve his energies, but he has begun to have strange visions of a mind so different from his own as to be other human, and knows he must stay alert and strong.

Charon Gubwa has invaded the Psychosphere. Twisted and evil, sexually and mentally warped, physically corrupt, Gubwa’s desires are simple: More. More drugs. More sex. More power. More of the Earth under his dominion.

Richard Garrison must battle Gubwa in the Psychosphere and on Earth. And he must win, no matter the cost to himself or those he loves, or all mankind will be lost.

An invasion from an alien dimension! That would be horror enough in itself: the thought of monstrous beings stalking the Earth. But how much more nightmarish if the invaders were each and every one . . . VAMPIRES!

Searching the infinite parallel time-streams of the metaphysical Mobius Continuum for his long-lost wife and son, the Necroscope Harry Keogh discovers that Soviet scientists have accidentally opened a portal to mankind’s worst nightmares. The lethal terror of Chernobyl is a mere bad dream in comparison.

THE SOURCE of all Dark Legends can now be reached by any who dare pass through the Gate. And by some who do not dare – but who have no choice . . .

Spacer Chan Dalton is torn between two masters. The pacifist aliens who hold Earth under Quarantine want him to find out why their starships have been disappearing in the Geyser Swirl, the Bermuda Triangle of the galaxy. Earth’s military, which has secretly discovered a way to break the quarantine, assumes that someone out there is making ships vanish, including Earth’s, and wants Dalton to find the culprits and hopefully stop them – with extreme prejudice, if necessary. The trouble is, the aliens hold the taking of intelligent life, even in selfdefense, to be the greatest of sins. It was Earth’s violent ways (in defense of the damned pacifist aliens!) that led to the quarantine in the first place -and if Dalton is forced to fight, it will unveil, and so destroy, Earth’s final chance to reach for the stars again. So when Dalton does indeed discover the hostile invaders responsible for the lost starships, he is faced with an impossible decision: Fight and lose access to space forever; or allow a rapacious enemy to run riot over all that he holds dear…
