Following the human vs prador war, Ian Cormac signs up with Earth Central Security. He's sent out to restore order on worlds devastated by alien bombardment. But he learns humanity can be far more dangerous - even those closest to him.

Amidst the tragic ruins left by wartime atrocities, Cormac discovers in himself the cold capacity for violence. It's a quality that'll make him one of Earth's top agents. Haunted by childhood memories of a sinister scorpion-shaped war drone, and the burden of losses he doesn't remember, he'll discover some hard truths. These will set him on a course of vengeance, where he'll have to use all his hard-won skills just to stay alive.

In the end he'll become Agent Ian Cormac. And it might just be enough to save the Polity itself . . .
