In the near future, a “brain-computer plague” breaks out. When people upload their consciousness to the quantum cloud, they contract a virus. Their physical bodies mutate into “corroded husks,” half-machine zombies, while their consciousness in the cloud splits into “data ghosts” that wander the networks of the ruins. Amid the apocalyptic crisis, humanity faces threats to both mind and body, and must explore the meaning of survival, sacrifice, and resistance.
