It's been nearly 200 years since the collapse of the Confederacy, the last government to claim humanity's colonies. So when signals come in revealing lost human colonies that could shift the power balance, the race is on between the Caliphate ships and a small team of scientists and mercenaries. But what awaits them all is a threat far beyond the scope of any human government.
