For years, pilots who merely looked like soldiers were adequate. They filled the mechs. They filled roles. They supported Spann and his genetic offshoot of pure-blooded warriors known as the Superba. Spann's dream of absolute power ends with a single, crushing blow as a new enemy strikes at the Realm, leaving no survivors—followed by a mad dash to find fighters who can stand up in the old ways, using the mechs gifted to humanity by their oldest allies. Even in the midst of war, there is hope.

Fergus Ferguson has been called a lot of names: thief, con artist, repo man. He prefers the term finder. His latest job should be simple. Find the spacecraft Venetia's Sword and steal it back from Arum Gilger, ex-nobleman turned power-hungry trade boss. He’ll slip in, decode the ship’s compromised AI security, and get out of town, Sword in hand.

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

Prince, a charismatic (and lackluster) real-estate agent with a complicated past, gets a once-in-a-lifetime opportunity to make it to the literal top of the business—fly an advanced spaceship known as “The Kepler” to an alien planet, where he will resume his career as an intergalactic realtor—selling luxury homes to the ultra-rich and live like the king he always knew he was. But when the plan falls short, and Prince discovers the dark forces manipulating his life on Matlitodus, he finds himself in the middle of an intergalactic scheme.

In the year 2420, war looms between the galaxy's two most powerful empires: the tyrannical Theocracy and the protectionist Commonwealth. Caught in the middle sits the occupied outpost system Cadiz, where young officer and aristocrat Katherine "Kat" Falcone finds herself prematurely promoted at the behest of her powerful father. Against her own wishes, Kat is sent to command the Commonwealth navy's newest warship, Lightning.

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.

For years, while Iran and North Korea kept Western diplomats busy, China and Russia have been quietly seeding the US with spies and soldiers. Now, a silent army of occupation lurks inside US borders, and for America, it is already too late. When the assault begins—via an EMP strike that disables the US electrical grid and neutralizes her defenses all in one fell swoop—the US is caught completely unprepared. The nation is lost, and it is up to ordinary citizens to defend their cities, towns, neighborhoods, or even just their families.

You can't militarize space. This one rule has led to decades of peaceful development of space programs worldwide. However, increasing resource scarcity and a changing climate on Earth's surface is causing some interested parties - namely India, the North American Union, and the Sinese Federation - to militarize. The discovery of a strange artifact by Dr. Alayna Wong precipitates a crisis. What appears to be a hitherto undiscovered comet is soon revealed to be an alien structure on a cometary trajectory toward the sun.

Ex-Army paratrooper Griffin “Fin” Brooks thought he left danger behind when his battlefield injuries forced him to pursue a new career in marine biology. But one fateful night off the coast of South Africa, a ship nearly crashes into him and his loyal golden retriever, Jacques. Not just any ship. A starship. Though its alien pilot is dead, the rare extraterrestrial animal inside is not. Fin learns the creature is being smuggled across the galaxy when a pair of interstellar visitors respond to the crash. But those same investigators accuse Fin and his dog of crimes he didn’t even know existed.

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.
