It is 1470 and the Wars of the Roses threatens to tear England apart. Overnight a man can find himself set against his brother or unable to trust the woman in his arms. For Margery, the beautiful and spirited ward of Warwick the Kingmaker, freedom is the only prize worth fighting for. Disgraced and banished to a nunnery after the philandering Edward IV ruined her reputation, she is determined that no man will ever decide her fate again. But the king has already set in train a deadly game of cat-and-mouse that will pit Margery against his enemies, and the enigmatic man who wants her. Her place in Warwick's household makes her the ideal choice as his secret courier to France to help avert the inevitable bloodbath the Lancastrians are plotting.
Torn between loyalty to her cause and a dangerous attraction to a man she should despise, Margery's mission becomes a deadly race against time to outwit her enemies and save the House of York.
