Time is a fragile thing. When an assassin known as The Timebreaker begins altering history with a series of strategic murders, the world is thrown into chaos. Charlotte Seina, an elite agent of ChronoGuard, is sent to unravel the mystery behind the deaths and the criminal manipulating time itself. But nothing is as it seems. As she delves into the mission, Charlotte crosses paths with Calyx Antonelli, a brilliant forensic historian whose knowledge of the past proves invaluable. Together, they travel through key moments in history—from the assassination of Leonardo da Vinci to the hidden political shifts of 1920s New York—chasing shadows of an elusive enemy who can rewrite the past with each death. As their investigation takes them deeper into the folds of time, Charlotte and Calyx's growing connection challenges the laws of ChronoGuard. Time is not only the enemy but also their greatest obstacle. With the fate of history hanging in the balance, they must decide: can their love survive the greatest paradox of all, or will the cost of saving time be their final sacrifice?
