We colonized 700 planets. Humankind enjoyed the benefits of expansion room and the end of wars. We even disbanded our military. Then the Krall found us. The Krall have used thousands of years of combat to select the genes of the strongest and fastest warriors. They are a species determined to dominate the entire galaxy, through destruction and annihilation of every opponent.

Koban is an uninhabited high-gravity planet with impossibly fast savage animals, which employ organic superconducting nerves. This deadly world is where the Krall tested humans for war capability.

Zac was alone in the middle of the forest when the world changed... The whole planet was introduced to the multiverse by an unfeeling System... or God.

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.

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....

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

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.

Jack Rust was a disillusioned biologist with a PhD—almost. When an extraterrestrial AI calling itself the System invaded Earth and thrusts it into a world of aliens and violence, the least Jack hoped for was gaining access to magic.

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

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. He believed his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble. But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him.
