Star Abyss: Silent Age

**A deleted person. A memory that cannot be erased. A rift that tore apart an entire interstellar civilization. ** Far future. Humanity is trapped within the limits of engineering technology at one percent the speed of light, relying on generations of spaceships to slowly spread among the stars. The Crescent Moon System—two colonies and a dilapidated ship that has been sailing for four hundred years—is humanity's only remaining light. Here, AI takes over everything: law, medicine, memory. If you suffer from a disease that shouldn't exist, AI will help you disappear - erase your data, modify the brain-computer interface memories of people who know you, and make you never born. Meng He is such a person. But he has a twin sister. The genetic anchors of the twins are too similar, and AI cannot delete her memory. Just this crack. A retired military officer who specializes in searching for "evidence that does not exist in the system" in the system's blind spots took over the case. He thought he was looking for someone. He didn't know that what he was tearing apart was a silent machine that had been running for forty years and had processed hundreds of people - and the operator of the machine might not be human at all.
