Disguising herself as a human is easy for shapeshifter Alira. Living as one turns out to be harder than she'd expected. And imitating a human well-known to millions on all the colony worlds may have been a mistake. To make matters worse, the harvests of knowledge and memories she's gathered from the dead aren't adequate to fully understand her assumed role-unless she surrenders control to the one internal voice she thinks can make things right. But that harvest isn't willing to share the space in her head, and soon Alira is no longer sure which voice is his, and which is her own.Galen has vowed to help Alira succeed and follows her increasingly unbalanced directives, until he realizes that her harvests have corrupted her conscience, maybe even her sanity. Galen has never been a leader. But as the crisis screams toward them, he must make a choice: abandon their people to save Alira or sacrifice her to save them all.
