Walking the streets of our cities are the Others. These men and women are guardians of the Twilight, a shadowy parallel world that exists alongside our own. Each has sworn allegiance to one side, fighting for good, or for evil. But outside the battles that rage between Day and Night now comes a greater peril, one which threatens their very world.
At Moscow airport Senior Light Other Anton Gorodetsky overhears a child screaming about a plane crash. He discovers that the child is a prophet - a supernatural being whose predictions come true if they are heard by humans. When the catastrophe is averted, Gorodetsky senses a disruption in the natural order, one that is confirmed by the arrival of a dark and terrifying predator.
From the Night Watch headquarters Gorodetsky travels to London, to China and across Russia in search of clues, unearthing as he goes a series of increasingly cataclysmic prophecies. He soon realises that what is at stake is the Twilight itself - and that he alone has the power to save it.
