Detective Serena Voss built her career on the pursuit of justice—until one compromised case fractured her resolve and left her haunted by a single, unforgivable choice. Years later, a string of vigilante killings grips the city, each victim a figure who once escaped the law. The signature is always the same: a blood-red ledger left at the scene, each page recording their unpunished crimes.

As public opinion sways in favor of the unknown executioner, Serena races to uncover the truth behind the Ledger Community—an underground movement that operates beyond police control. But when one of the ledgers arrives on her desk with her own name written in ink, the hunt turns personal.

Now forced to confront her buried guilt, Serena must navigate a dangerous web of secrets, moral ambiguity, and shifting loyalties. Each clue she uncovers draws her closer to the enigmatic mastermind, whose motivations may not be as clear as they seem.

As the lines between justice and vengeance blur, Serena faces the ultimate question: How far will she go to atone for the sins of her past—before the ledger writes her final chapter?
