In 2035, in San Francisco, quantum physicist Arthur Crowder's wife was killed in a "perfect murder." There were no fingerprints, no witnesses—only half of a high-tech alloy button, clearly belonging to future technology. To uncover the truth, Arthur infiltrated his own creation, the "Novous Timefold Experiment," but a malfunction in the equipment threw him into parallel timelines. He gradually discovered that in each timeline, a different version of himself was enacting vengeance in various ways. All clues pointed to a more terrifying truth—the murderer was Raymond Stone, his mentor, who had "died" twenty years ago due to an experimental failure caused by Arthur himself. After crossing twelve timelines, Arthur was forced to choose between saving his wife and maintaining the stability of time itself. Ultimately, he uncovered an even darker conspiracy—the collective manipulation of human memories.
