While her starfaring people are being hunted by an implacable enemy, a young caver discovers a traitor in their ranks and must undertake a transformative journey across the galaxy to save everything she has ever known.
Persecuted for their worship of the Endless—an ancient, galactic-spanning race of god-like power, who disappeared eons past—the Pilgrims escaped the world of Raia almost a century ago, fleeing the despotic rule of the United Empire in a dozen space-faring fleets.
Young Pilgrim Sewa Eze wants nothing more than to become a caver and head into the depths of deserted moons, asteroids, and worlds to secure whatever the fleet needs: precious resources, Endless relics, even Dust. However, when she discovers a strange device deep in the ice of the comet they shelter on, it becomes clear dark forces are afoot. Selected for a leadership role at the Ceremony of Duties, she must reassess her life, beginning with finding the traitor in their ranks who threatens her entire fleet’s existence.
The course of Sewa’s life changes forever as she is forced to confront treachery, discover the secrets of the ancient past and travel to the very heart of the tyrannical United Empire.
