When vigilante killer Sadie Slawter—known to the press as The Padlock Killer—infiltrates the Serial Killer Holiday Agency, a dark web network offering “vacations” for murderers, she plans to destroy it from within. Her mission takes her to Barcelona, where she crosses paths with a brutal lineup of predators and a haunted Englishman, Samson Harris, traveling with his mute daughter, Maerose.

When the girl is abducted, Sadie’s violent crusade turns personal. Forced to confront her own trauma, she must choose between the thrill of vengeance and the possibility of redemption.

Holiday Kill is a blood-stained, character-driven thriller where morality dissolves and predators become prey.
