The war with the deadly Host continues, only now they have secret alien allies bolstering their efforts. Our former general has defected. Our fleet of battleships took a battering in the first battle. And I’m trapped in another part of the galaxy trying to find my parents and, ultimately, my way home. The situation looks bleak, but I have ancient Navigator technology at my disposal, and I'm mad as hell. Then there's this weird alien information bomb inside my head that I can't access despite it suggesting great power. With new enemies lining up to thwart my plans, I’ll need to muster all the courage and skill if I’m to beat the odds and get back to Coalition space before the Host overwhelm my people and take over the galaxy. If the Host win, the Coalition worlds will burn. Its population will be slaughtered, and there will be no hope for any of us. But I have a ragtag crew of heroes willing to push back against our foes regardless of the odds. The Coalition will prevail once more, even if I have to die for the cause. For fans of Star Wars, Firefly, Battlestar, and Guardians of the Galaxy.

The Solar Federation has been stable for decades - until a few days ago when leader of the abbots (artificial, biological robot) has mysteriously disappeared. His fate threatens the unsteady peace between human and machine. Detective Harlan Rubik has but a few chances left to save his career after a string of failed cases. When he’s tasked with finding the abbot leader, he uncovers a deadly conspiracy perpetrated by a shadowy group called Vanguard, whose tendrils reach to the highest echelons of government. It will take all of Harlan’s skills to uncover the truth behind this dark force. If he fails, it will be the end of his life as he knows it. When scientist Irena Selles is attacked by a rogue abbot while working in one of Earth’s last remaining scientific outposts, she’s forced to flee for her life and hitch a ride back to Atlas Station with the help of a crew of salvagers. Harlan, seeing a pattern between their cases, joins forces with them. Together, they set out to find the truth behind Vanguard. With so few humans left and scattered across the Solar system, an abbot rebellion would be fatal to humanity’s continued existence. Harlan, Irena, and their ragtag crew of allies will journey through space stations, colonies, and the darkest parts of the Solar system if they’re to stop Vanguard rising. But will their combined efforts be enough? And what do they truly want?

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. We had assumed they were beaten for good. We were wrong. 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. Against their wrath, we must stand. We’re outnumbered and unprepared. If we lose, we lose everything. 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. If I fail, the Coalition will fall, and the Host will consign us to a distant memory. I refuse to let that happen. I will fight to my last breath for the Coalition’s survival. For fans of Star Wars, Firefly, Battlestar, and Guardians of the Galaxy.
