We Speak No Treason: The White Rose Turned to Blood: Book 2

As Edward IV lay on his deathbed, he had no knowledge of the dark conspiracy which was to surround his son, and his brother Richard after his death. This is the story of the two tumultuous years of his reign - told by the Man of Keen Sight, who befriended and then betrayed him, and by the Nun, who had known him in happier times.
