In Mirror City, a futuristic metropolis where “memory retrospection” is the cornerstone of the justice system, truth is encoded and crime can be watched. Ling Ye, a memory examiner who exiled himself after a wrongful verdict in his past, is forced into a murder case so flawless it seems impossible to challenge. The victim was one of the creators of memory technology, and the evidence points to a suspect with no apparent motive. As Ling Ye peels back layer upon layer of fabricated memories, he finds himself falling into a vast conspiracy woven from power, ambition, and forbidden technology. In this city where truth and falsehood are impossible to distinguish, he must not only hunt down the killer but also fight a specter capable of rewriting reality, and confront the guilt buried deep within himself.
