Today, Battle Fleet 921 is returning to Earth. It hasn't been seen by human eyes since our blissful day of Annexation. But what should be a joyful occasion, a chance to grovel at the feet of superior lifeforms, is rapidly becoming a nightmare.

Not everyone on Earth is happy with the demands of the Galactics. Earth has built up her military for decades, and now she might lose everything in a foreign war no one understands. As the man who has killed more Mogwa than any other human in history, McGill is approached and given a mission. He has a fateful decision to make.

The Genevians are at war with Nietzschea...and they’re losing. In a last-ditch hope, the Genevian mech program was founded.

Yet few wished to undergo the brutal process, and so criminals were used, their minds enslaved by control chips and obedience enforced through discipline.

The UFS Phoenix returns to Homeworld, after more than three years of searching the galaxy for a way to save humanity from the looming AI threat. Many Fleet captains are unhappy with their own command, following the massive casualties of Nia's first strike. Some say that Captain Erik Debogande is the war leader humanity truly needs.

A secret that could tear Fleet, and Erik's powerful family, apart.

More than 50 years after publishing his first story, Hugo Award-winning author Asimov remains one of the great names in science fiction. Almost single-handedly he transformed the field from the romantic and Gothic legacy of Jules Verne and Edgar Rice Burroughs into the rational, clear-minded genre that exists today. This selection of some of Asimov's most enduring and unforgettable stories is read by the author himself. These vintage tales encompass the full range of Asimov's versatility, while displaying his puckish sense of humor.

On a cold spring night in 1952, a huge meteorite fell to earth and obliterated much of the East Coast of the US, including Washington, DC. The ensuing climate cataclysm will soon render the Earth inhospitable for humanity, as the last such meteorite did for the dinosaurs. This looming threat calls for a radically accelerated effort to colonize space and requires a much-larger share of humanity to take part in the process. Elma York’s drive to become the first lady astronaut is so strong that even the most dearly held conventions of society may not stand a chance against her.

The Phage War had been a devastating conflict for the Terran Confederacy. Even with the destruction of their terrifying, implacable foe, humanity is still reeling. Political alliances are crumbling, and their mighty fleet is in tatters. There is nothing to celebrate, even after such a complete victory. They soon learn that there are other stellar neighbors - and they've been watching the conflict with great interest. One species comes with an offer of friendship and alliance, but humanity is weary and distrustful.

The colony on Haven-7 has gone rogue. The colonists have split into two factions: the Techborn and the Dusters. The Techborn have always ruled the planet. They control the remnants of the crashed starship that brought humanity to this new world. The Dusters… they eat Techborn dust. Now, the Techborn strength is waning. Their weapons are getting old, and radiation leaks from the aging reactors have created mutations. Some of these, like their brutish troops known as Tuskers, have proven useful—but others are abominations.

Since fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have - just barely - survived one crisis after another: the rebellion of their human slaves, the relentless questing of the species of Known Space, the spectacular rise of the starfishlike Gw'oth, the onslaught of the genocidal Pak. Now fresh disaster looms, as though past crises have returned and converged. Who can possibly save the Fleet this time?

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

When unforeseen circumstances during an innovative—and unsanctioned—commercial asteroid-mining mission leave two crew members stranded, those who make it back must engineer a rescue, all while navigating a shifting web of global political alliances and renewed Cold War tensions. With Earth governments consumed by the ravages of climate change and unable to take the risks necessary to make rapid progress in space, the crew must build their own next-gen spacecraft capable of mounting a rescue in time for the asteroid's next swing by Earth.

The Darshik war machine is flagging, but the war is far from over. Even as an exhausted Federation military tenses up for a counterattack after repelling the last Darshik invasion, reports are coming in of a new, more powerful class of ship that's striking deep into Terran space. Captain Jackson Wolfe has been given the fleet's newest, most advanced destroyer and tasked with eliminating this new threat before it can claim any more human lives. What he finds, however, is immeasurably more dangerous than just some new class of starship....
