Ambrosia Severn is a talented young orthopedic surgeon, and was about to branch off in an exciting new direction in the field of limb replacement, when she made that one fateful mistake—she took a seacoast vacation. The man who had watched her for fifteen years made sure she was dead—but only to the world. Niven is a descendant of Quen star-lords stranded on Earth thousands of years ago. His original mission directive was simple: Protect the beautiful and talented young doctor. He re-wrote the script according to his heart's desire and today Amy is very much alive among the people whose ancestors came down from the stars. She is grateful to Niven's kinfolk for offering her refuge when she most needed it, but she also thinks they've been hiding their homeland long enough. Especially now, when Niven's two sons keep her busy, she doesn't want them to grow up in the isolation of the elite island society. However, there is a difference between a measured exposure of the Island, and ripping off its cloaking screen. But that's precisely what Persis, the ruthless siren wants to do—and in the process destroy the world that's hosted her ancestors.

The Island is a sanctuary but the danger is far from over. Niven now must expand the protection to their two children.
