In the drowned depths of the Pacific Ocean, humanity survives inside a massive underwater city called Pacifica Prime. Maintenance technician Silas Vance lives a monotonous life repairing failing systems—until he discovers a horrifying truth: the city’s power is generated by harvesting the memories and emotions of its citizens during mandatory cognitive screenings.
As Silas uncovers a conspiracy buried beneath decades of propaganda, he learns that the ruined surface world may not be dead after all. Hunted by the authorities and haunted by the pieces of himself already stolen, he must decide whether to expose the truth and risk everything—or remain another hollow shell in the last ocean city.
