Bloody civil war over the last habitable zones of the cosmos. Political unrest, militaristic police forces, dire threats to the Solar System… Humanity is on the ropes, and after years of fighting a two-front war with losing odds, so is North American Defense Corps officer Andrew Grayson. He dreams of dropping out of the service one day, alongside his pilot girlfriend, but as warfare consumes entire planets and conditions on Earth deteriorate, he wonders if there will be anywhere left for them to go. After surviving a disastrous space-borne assault, Grayson is reassigned to a ship bound for a distant colony – and packed with malcontents and troublemakers. His most dangerous battle has just begun.
