Newly divorced, she buries herself in her work. Thea keeps Caya Lindemay, a young changer in protective custody. Caya loathes her luxurious prison, but still helps the president whenever her clairvoyant visions are of use. As the two women acknowledge the growing romantic tension between them, Caya lives on the hope Thea will finally set her free. As a catastrophe of devastating proportions approaches Pathfinder, Caya risks everything to help the woman she loves and their people. If she fails, it may mean the end of the Exodus mission and potential annihilation.
