Hard Science Fiction Space

Seven years after the indomitable Doug Stavenger has realized his cherished dream of establishing a colony on the inhospitable lunar surface, Moonbase is a thriving community, a marvel of scientific achievement created and supported by nanotechnology: virus-sized machines that can build, cure, and destroy. But nanotechnology has been declared illegal by the home planet’s leaders, and a powerful despot is determined to lay claim to Stavenger’s peaceful city - or obliterate it, if necessary.

Tanis and Sera have taken the I2 to Khardine, the new capital of the Transcend, and must now travel to the Inner Stars and meet with Scipian Empress, Diana - who they hope will be an ally to the Transcend.

But Empress Diana has her own plans for the Inner Stars, and while they may dovetail with the Transcend's for now, they may not always do so....

In the early 22nd century, humanity has spread through the solar system - and their electromagnetic signals have traveled hundreds of light years. An alien race called the Oghaldzon has decided that mankind is dangerously insane...and must be forcibly taken under control. The invasion fleet's technology is decades ahead of Earth's best. They have more ships than the human fleets combined, and a seemingly-inexhaustible number of ground troops. And they're not afraid to kill billions of people.

Dixon's survival relies on his skills as a pilot and willingness to do whatever it takes.

When aliens attack and obliterate his solar system, fifteen-year-old Cody Ford narrowly escapes on a battered shuttle, carrying a precious cargo: the last remnants of humanity. Forced to think fast, Cody teams up with a brilliant young engineer named Ellaz to scavenge the wreckage of a lunar shipyard and construct a new starship – a ship capable of outrunning annihilation and carrying a warning to the rest of the galaxy. But building a ship is only half the battle. Cody and Ellaz must master cutting-edge technology, confront impossible choices, and face a chilling truth: sometimes, saving...

A cold war between the American-led Alliance and the Domination, rivals in the Draka conquest, erupts in a space confrontation that will decide the freedom or slavery of humankind.

The secretive Roma Union has stepped forward. The warlike Maraukians are coming, and humanity must rally together or shatter into oblivion.

April is an exceptional young lady and something of a snoop. After a chance encounter with a spy, she finds herself involved with political intrigues that stretch her abilities. There is a terrible danger she, and her friends and family, will lose the only home she has ever known, and be forced to live on the slum ball Earth below. It's more than an almost fourteen year old should have to deal with. Fortunately she has a lot of smart friends and allies. It's a good thing because things get very rough and dicey. They challenge the political status quo, and with a small population the only ...

The Theocracy has been dead for 20 years, and the Polity rules on Masada - but it is an order that the rebels of the Tidy Squad cannot accept, and the iconic Jeremiah Tombs is top of their hitlist. Tombs, meanwhile, has escaped his sanatorium. His insanity must be cured, because the near-mythical hooder, called "the Technician", that attacked him all those years ago, did something to his mind even the AIs fail to understand. Tombs might possess information about the suicide of an entire alien race.

Years have passed since Earth encountered its first known interstellar object: Oumuamua. Now an even larger one has been discovered, following the exact same trajectory as its predecessor. Scientists around the world theorize that this can no longer be passed off as mere coincidence - the new contact must be an artificial construct of some kind.

Thousands of years ago, Earth's terraforming program took to the stars. On the world they called Nod, scientists discovered alien life - but it was their mission to overwrite it with the memory of Earth. Then humanity's great empire fell, and the program's decisions were lost to time. Aeons later, humanity and its new spider allies detected fragmentary radio signals between the stars. They dispatched an exploration vessel, hoping to find cousins from old Earth. But those ancient terraformers woke something on Nod better left undisturbed. And it's been waiting for them.

The virtual persona of a long-dead visionary entrepreneur threatens to incite a revolution from space that could topple Earth's powerful and repressive religious-technological dictatorship in this ingenious science-fiction classic.

Three against the stars! A sky pirate armed with superior weapons of his own invention.... First contact with an alien race dangerous enough to threaten the safety of two planets.... The arrival of an unseen dark sun whose attendant marauders aimed at the very end of civilization in this Solar System.... These were the three challenges that tested the skill and minds of the brilliant team of scientist-astronauts Arcot, Wade, and Morey.

Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe. Bob and his copies have been spreading out from Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece.

The day that changed Melody's life was like any other over the previous two years. She'd found she had a gift for writing, and her career as an author had almost healed the pain of losing her job. When the Secret Service rang her bell, everything changed. Something was nearing Saturn…and it was slowing down. Had she been right about the object?

Generations ago, nine ships headed into the unknown to explore a distant star called LQ Pyx. Eons later, the convoy has returned to LQ Pyx to begin work on the Web, the alien megastructure that covers the star. Is it a Dyson Sphere, designed to power a civilization as everyone believes - or something far more sinister? Meanwhile, Planet United's littlest convoy, long thought to be lost, reemerges in a different sector of deep space. What they discover holds the answers to unlocking the Web's greater purpose.

The war raged across the galaxy. Billions had died, billions more were doomed. Moons, planets, the very stars themselves, faced destruction, cold-blooded, brutal, and worse, random. The Idirans fought for their Faith; the Culture for its moral right to exist. Principles were at stake. There could be no surrender. Within the cosmic conflict, an individual crusade. Deep within a fabled labyrinth on a barren world, a Planet of the Dead proscribed to mortals, lay a fugitive Mind. Both the Culture and the Idirans sought it....

This classic science fiction masterwork by Isaac Asimov weaves stories about robots, humanity, and the deep questions of existence into a novel of shocking intelligence and heart.

Commander Scott McNabb and the crew of the science vessel, Hermes, are three years into a five-year-long survey of the asteroid belt when they discover a derelict spaceship in orbit around a binary asteroid. The ship contains an experimental quantum device, lost while en route to a research colony on Europa.

Major Richards needs to get out of the Sol System. Demoted by the military and hung out to dry, the media labels her the Butcher of Toro. Despite her soiled record, Tanis still one of the best military counterinsurgency officers in the Terran Space Force. They need her to find the terrorists responsible for trying to destroy the GSS Intrepid, a massive interstellar colony ship in the final phases of construction at the Mars Outer Shipyards.
