In the dazzling "Mirror City", memories can be repaired, edited and even traded. Lin Mo, a top memory restorer, had a perfect family and career until a mysterious woman codenamed "Zero" appeared and claimed that his life was a carefully woven lie. A fragment of memory that does not belong to him - the rusty swing - becomes the fulcrum for him to move the entire false world. In order to find his true self, Lin Mo was forced to step into the memory maze built by lies and technology, only to find that he was already a prisoner of this splendid city, and the price of the truth was far heavier than he imagined.
