A stunning trip across the galaxy and into the future

Focusing on Richard Ayrault, a stockholder of the Terrestrial Axis Straightening Company, A Journey in Other Worlds takes readers across the solar system to Jupiter and Saturn. On Jupiter, Astor creates a fantastically outsize world of gushing volcanoes, crashing waterfalls, and otherworldly flora and fauna. In contrast, his Saturn is an introspective and philosophical land. While Ayrault’s journey is the main attraction, it is Astor’s vision of a future with maglev trains, a police force equipped with cameras, and an interconnected network of phones, solar power, wind power, and air travel that will astonish.

At the turn of the twentieth century, few would believe that mankind is being watched from above. But millions of miles from Earth, the lords of the Red Planet prepare their armies for invasion, waiting for the moment to strike. 

When they land in the English countryside, baffled humans approach, waving white flags, and the Martians burn them to a crisp. 

The war has begun, and mankind doesn’t stand a chance. As Martian armies roll across England, one man fights to keep his family safe, risking his life—and his sanity—on the front lines of the greatest war in galactic history.

H. G. Wells’s groundbreaking novel, adapted to radio and film, among other mediums, by visionary artists from Orson Welles to Steven Spielberg, remains one of the most chilling, unforgettable works of science fiction ever written.

In the uncharted wastes of Antarctica, an exploration party from Miskatonic University encounters a gory sight when they discover their advance team’s camp has been destroyed and its members slaughtered. 

There is no evidence of what happened except a series of burial mounds, six of which contain dead specimens of unknown species. Eight similar tombs are empty, but they haven’t been broken into—they’ve been broken out of.

What began as a search for knowledge soon becomes a terrifying confrontation with the true nature of the world and the universe in all its stark blackness and unyielding oblivion. 

For mankind is not—and never has been—the bright light of creation. It’s all a mistake, an insignificant stain of existence, forgotten by an unwitting and indifferent creator . . . until now.

A gifted gambler fights to survive on a hostile planet in this classic novel from the creator of science fiction antihero the Stainless Steel Rat.

The gravity is twice that of Earth. The weather is an unpredictable maelstrom. All species of life, both plant and animal, monstrous and microscopic, are lethal. And the environment is drenched with radioactivity.

This is planet Pyrrus, where telepathically gifted gambler Jason dinAlt has ended up after scamming a government casino out of a fortune. 

A small, fortified town stands against the nonstop natural onslaught, and its people are the descendants of hardened survivors. But there are some who exist outside the city—the “grubbers,” humans living in harmony with the nightmarish surroundings who share a mutual hatred with the technologically superior city dwellers.

These people fascinate Jason because they share his psionic abilities. And with their help he soon realizes that Pyrrus is more than just a planet. It’s alive. It’s intelligent. And it’s angry.

The first installment in the groundbreaking Lensman series, one of the greatest space opera sagas of all time

Nevia, located many light years from the Earth’s sun, is running out of iron, the primary source of energy for the planet’s dominant amphibious race. Armed with technology that can extract iron atoms from anything it encounters—rock, machinery, man-made structures, even human blood—the Nevians set their sights on a rich lode of the precious element: the planet Earth. 

Descending on its unsuspecting target, the Nevian space-ship destroys the city of Pittsburgh and its defenseless inhabitants before heading home with three human specimens in its hold. Among them is Conway Costigan, an undercover intelligence operative for the Triplanetary Patrol. 

From deep within the bowels of the enemy ship, Costigan must do the impossible: find a way to defeat the Nevians before every man, woman, and child on Earth is annihilated.
