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.

There, he finds the material he’s been sent to recover, along with something more. A brand-new form of ancient alien life.

Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.
