Young Fitz, the illegitimate son of the noble Prince Chivalry, is ignored by all royalty except the devious King Shrewd, who has had him tutored him in the dark arts of the assassin. He has barely survived his first, soul-shattering mission, and returns to the court where he is thrown headfirst into the tumult of royal life. With the King near death, and Fitz's only ally off on a seemingly hopeless quest, the throne itself is threatened.
