It is 1470, and the Wars of the Roses threaten to tear England apart. Overnight a man can find himself set against his brother or unable to trust the woman in his arms. For the beautiful and spirited ward of Warwick the Kingmaker, Margery, freedom is the only prize worth fighting for. Disgraced and banished to a nunnery after the philandering Edward IV seduced her, she is determined that no man will ever decide her fate again. Torn between her loyalty to her cause and a dangerous attraction to a man she should despise, Margery's mission becomes a race against time to outwit her enemies and her husband.
