Lady Lily Spark has been missing, presumed dead, for years. Now she's back in England, and in possession of a secret that could change the course of history. And she has no intention of giving it-or herself-up to anyone.
John Tacitus Ware doesn't know Lily's secret. All he knows is that she has one-and he'll have to win it from her if he wants to regain his place at the heart of British diplomacy.
John and Lily are playing a dangerous game, with war and peace as the stakes. But as John's ruthless ambition collides with Lily's skilled manipulation, the attraction between them may change the rules for good.
