Querry and the members of Survival Colony 9 have defeated a whole nest of the creatures called Skaldi, who can impersonate humans even as they destroy them. But now the colony is dangerously low in numbers and supplies. Querry's mother is in command, and is definitely taking them somewhere--but where? Some secret from her past seems to be driving her relentlessly forward.

When they do finally reach their destination, Querry is amazed to discover a whole compound of humans--organized, with plenty of food and equipment. But the colonists are not welcomed. Everything about them is questioned, especially by Mercy, the granddaughter of the compound's leader. Mercy is as tough a fighter as Querry has ever seen--and a girl as impetuous as Querry is careful. But the more Querry learns about Mercy and the others, the more he realizes that nothing around him is as it seems. There are gruesome secrets haunting this place and its people. And it's up to Querry to unearth the past and try to save the future in this gripping conclusion to the Survival Colony novels.
