Elvene, a solo Space Corps agent, is on a reconnaissance mission when she is ambushed by space marauders: militaristic robotic drones, designed to hunt and kill. She escapes by taking refuge on an uncharted planet, where she discovers the Kiri, an unknown tribe living a subsistence life on an ocean archipelago. They have no knowledge of her world nor her of theirs; but they readily adopt her and give her the title of Ocean Woman. Elvene responds in kind, temporarily forgetting the tribulations of her own world. Inevitably, however, her past catches up with her and endangers the very people who embraced her. The Kiri not only challenge everything Elvene thought she knew about humanity, but provide a friendship and love that leads her to consider the ultimate sacrifice.
