Our universe is but a snow globe—an experiment born of desperation and hope. The true universe is unfathomably vast, teeming with life and untold wonders. And, it is enslaved. Created by ancient aliens in a daring gambit to understand the nature of the enemy, humanity is now asked to be the savior of a universe not their own. If they are to succeed, they must rise above not only their fractious past but the sins of their genetic ancestors to boldly embrace a future they never dared imagine possible.

It's the mid-21st century. The oceans are rising, the world's population is growing, terrorist organizations are running rampant, and it has become readily apparent that humanity's destructive nature is at the heart of the matter. When all faith in humanity seems lost, a startling proposal is announced: Solomon Chavez, the mysterious son of the world's first trillionaire, announces that he, backed by a consortium of governments and wealthy donors, will build an interstellar starship.

Reidon Ward will become a god. He doesn't know it yet, of course. Reidon was born weak, sickly, and small. Afflicted with a painful disease and abandoned by his parents because of it, he has had to fight tooth and nail for every minor advantage life has allowed him. However, his perseverance has not gone unnoticed, and when the most powerful artificial intelligence in human history takes an interest in him, things began to change quickly.

They won't settle for mere victory. They want to exterminate us. Every last one of us. A surprise attack has sent the Star Alliance fleeing for its life. A remnant of a remnant, their meager fleet—all that remains alive—flees to what seems like a safe harbor: a forgotten backwater planet called Earth. Join ace fighter pilot Chase as he teams up with the modern-day militaries of Earth and fights the last battle for the universe.

Get ready to experience two more origin stories in the Backyard Starship universe.

The galaxy’s worst bounty hunter just might be its most relentless hero. Esper Richelieu is a wizard with a mission: To make the galaxy a better place one lost soul at a time. Donning the trappings of an interstellar bounty hunter, she delves into the galaxy’s underworld to search out those most in need of help. Whether it’s a teenage runaway or an actor kidnapped by cultists, the victim comes first. Money is an afterthought. That confuses a lot of clients. But sometimes the best way to get someone to accept the help they need is to convince them to pay for it.

Out of the blue, a young Space Fleet officer's dream becomes reality: He's made captain of a starship. Just in time for the return of humanity's most terrible enemy, after 50 years of peace. To survive against this enemy, Captain Tad Thatcher will have to do more than learn how to become an effective commander, or how to wrangle his wayward crew. He will need to reinvent space combat. From scratch.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

As a sci-fi author with a hit TV show, I have a few ideas about what alien invaders are supposed to look like. In my stories, they’re technologically advanced monsters, with tentacles, and no faces. Turns out I was right about the technology. And about how angry they’d be. But the way they look…that’s more terrifying than even I could have imagined. They look exactly like us. Because they are us.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

It seemed the unthinkable had happened. Someone had actually targeted the Ghalian, an order of assassins known and feared across the systems. It was madness. Only a fool would go after the likes of them. But, it seemed, the galaxy had no shortage of fools. Retaliation most bloody was in order, and one man stood ready to spring into action. Hozark was his name, and he was no ordinary man. He was a Master Ghalian, an assassin skilled in the ways of death. Practical, mechanical, magical, to him it made no difference.

The mission is simple. Escort an emissary to an intergalactic peace summit. Try not to get in the way. Lt. Magnus and his 79th Recon Team have certainly handled worse, after all. But when an explosion rocks the tower and sends everyone into a panic, Magnus and his asset find themselves cut off from the rest of the team. Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death. The mission has officially changed. With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower.

As if nearly burning up in a freak accident on her way to Earth wasn't bad enough, Daisy had a whole mess of other trouble on her plate. Big trouble. And she was going to get to the bottom of it if it was the last thing she'd do, which it was starting to look like it very well might be. The thing is, Daisy had a simple rule for space travel. Don't blow up, and so far she'd been managing to abide by that, but mere survival wasn't enough.

Over the years, humans have grown used to their position within the empire, serving as soldiers and spacers for alien masters as well as building a place in the universe for themselves. But now, in the aftermath of a violent interstellar war that shattered the power of the Alphans, humanity has rediscovered its pride.

Cole Riker is a Slip Runner. A contractor tasked with finding alien salvage in exchange for credits. For an ex-smuggler like Cole, there’s a catch: Don’t break the terms of parole. That means doing things by the book. Find salvage, turn it in, get paid. But everything changes when a retrieval mission lands him in a previously unknown sector. There, he finds the material he’s been sent to recover, along with something more. A brand-new form of ancient alien life.

They tried to destroy our planets. Our way of life. They tried to send us into extinction. But we, the Coalition, fought them and won. That was a decade ago. They’re known as the Host: a cabal of aliens seeking to dominate our sector of space. And they’re back - with help from a powerful new enemy. We’re outnumbered and unprepared. But there is hope. An ancient race of long-dead but technologically advanced aliens called the Navigators have a ship called the Blackstar that could potentially turn the tide. That is if I, Kai Locke, a humble ship racer, can find it and learn how to harness its power in time.

Kalian Gaines has a secret; he just doesn't know it yet. He looks like us, he lives like us...but he is not one of us. Kalian knows nothing outside of his mundane life teaching history on 30th-century Earth, until a day like any other triggers a series of events that will tie his fate to that of humanity. A human handprint, embedded into a rock with alien script, is discovered on a moon that mankind has never set foot on. This discovery holds a secret, which will sweep Kalian into the heart of a conspiracy that has corrupted the galaxy for 200,000 years.

One starship will either save Earth or destroy her. A century ago our star erupted, destroying Earth's wormhole network and closing off trade with her colonized planets. After being out of contact with the younger worlds for so many years, humanity is shocked when a huge ship appears at the edge of the solar system. Our outdated navy investigates, both curious and fearful. What they learn from the massive vessel shocks the planet.

A mysterious terrorist organisation has carried out several attacks against the Federation and Klingon Empire. Tensions are running high in a region already crippled by conflict. The perpetrators are tracked to the Lembatta Cluster, a mysterious region of space whose inhabitants, the Renao, regard the Alpha Quadrant s powers as little more than conquering tyrants. The Federation are desperate to prevent more bloodshed, and have sent their most powerful warship, the USS Prometheus, into the Cluster to investigate the threat before all-consuming war breaks out.

When an ally reveals that his younger sister was seized and is being held prisoner on Earth, Taelon descends upon the blue planet, intent on freeing her and exacting vengeance. However, all does not go as planned. Before he can find her, Taelon is captured and becomes the subject of torturous experiments. For what feels like an eternity, all he knows is pain and fury...until a mind tentatively touches his own and a woman's voice forever changes his world.

Two hundred years after a nuclear apocalypse forced humanity to flee earth, humans still remember the most feared warriors of that planet - the Paratwa. These are genetically modified killers who occupy two bodies controlled by one vicious mind. The legendary Paratwa named Reemul, known as the Liege-Killer, was the strongest of them all. Now someone has revived Reemul from stasis and sent him to terrorize the peaceful orbital colonies of Earth. Is this an isolated incident, or has the one who unleashed this terrible power announced a gambit for control over the entire human race?

Before he was Oldtimer, he was Craig Emilson, a young doctor,sucked into military service at the outbreak of World War III. Enlisting to become a Special Forces suborbital paratrooper, Craig is selected to take part in the most important mission in American military history, a sortie into enemy territory to eliminate the world's first strong artificial intelligence.

Convicted criminal James Griffin-Mars is no one's hero. In his time, Earth is a toxic, abandoned world, and humans have fled into the outer solar system to survive, eking out a fragile, doomed existence among the other planets and their moons. Those responsible for delaying humanity's demise believe time travel holds the key, and they have identified James, troubled though he is, as one of a select and expendable few ideally suited for the most dangerous job in history.

Cobras are technologically-enhanced warriors bred to fight an alien menace no ordinary human can withstand. At the center of action, on the Cobra world of Aventine, is the legendary Moreau clan. While the Cobras are necessary in times of war, in times of peace, they are often reviled by those they have saved. Now, the Cobras have resisted a second invasion of the alien Troft forces, forcing the Troft to a stalemate - even converting some thoughtful Troft into uneasy allies against their kin.

After discovering a cache of Prothean technology on Mars in 2148, humanity is spreading to the stars---the newest interstellar species, struggling to carve out its place in the greater galactic community. On the edge of colonized space, ship commander and Alliance war hero David Anderson investigates the remains of a top secret military research station---smoking ruins littered with bodies and unanswered questions. Who attacked this post, and for what purpose?

When humanity reaches for the stars, our probes are destroyed. They crash into an incredibly advanced piece of technology: a massive force-field. Unknown beings have placed a barrier around our star and planets, enclosing us within. We’re locked inside a Great Sphere. Was this invisible obstacle built to imprison us - or to protect us? No one knows the truth, but it soon becomes clear the barrier has leaks. Aliens infiltrate and try to sabotage our efforts to escape our cage.

In AD 2600, the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems, and throughout inhabited space the Confederation Navy keeps the peace.

Fleet of Worlds takes a closer look at Human-Puppeteer (Citizen) relations and the events leading up to Niven's first Ringworld novel. Kirsten Quinn-Kovacks is among the best and brightest of her people. She gratefully serves the gentle race that rescued her ancestors from a dying starship, gave them a world, and nurtures them still. If only the Citizens knew where Kirsten's people came from.

In the year 2280, an alien fleet attacked the Earth. Their weapons were unstoppable, their defenses unbreakable. Our technology was inferior, our militaries overwhelmed. Only one starship escaped before civilization fell. Earth was lost. It was never forgotten. Fifty-two years have passed. A message from home has been received. The time to fight for what is ours has come.

Rose McKenzie may be far from Earth with no way back, but she's made a powerful ally - a fellow prisoner with whom she's formed a strong bond. Sazo's an artificial intelligence. He's saved her from captivity and torture, but he's also put her in the middle of a conflict, leaving Rose with her loyalties divided. Captain Dav Jallan doesn't know why he and his crew have stumbled across an almost legendary Class 5 battleship, but he's not going to complain. The only problem is, all its crew are dead - all except for one strange, new alien being.
