But when tasked by the king to uncover a traitor, he discovers instead a conspiracy, and a woman whose courage awakens terrible temptations. To save her is to risk everything. To love her might cost him his life. Lady Sarah Percy knows that Rivenham is the devil in beautiful disguise-and that the dark attraction between them is as dangerous as the nightmare in which her family is trapped. But when war breaks out, she has no choice but to place her trust in her dearest enemy-and hope that love does not become the weapon that destroys them both...
