The last thing Commander Neenja KahSandra wants is to be babysitting Zoem Malderyn, an orphan who can barely remember her past, and who has just regained consciousness after being used as a template for an army of changer clones. Despite herself, she comes to care for Zoem, whose courage and vulnerability is difficult to resist.

But as Zoem starts to remember more, a deadly countdown to destruction occurs inside her. She needs to discover why the malevolent changers programed her, and how to stop herself from carrying out their plan. Can the famous sisters, Caya and Briar Lindemay, help save Zoem and the Gemoconians, or will Zoem end up sacrificing herself—before she kills them all?
