Five master assassins: they are the judges, the silent executioners, and they will find the guilty. Five who keep the world in balance. Five with very different stories: One who loves her birthright; one who loathes it. One careless; one contradictory. And one, just a child, who has never killed at all. When all they know is threatened, they must embark on a difficult chase to face a mysterious foe. But the enemy may be closer than they think.
