Shadow of the Scorpion is a standalone prequel to Neal Asher’s explosive Agent Cormac series. Some secrets are too hard to bear . . . 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.

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.
