Imogen, warrior of the Kirkellan tribes, has never wanted to be anything else. But when the long war between the Kirkellan and the country of Ruskald ends, the terms of the peace treaty require Imogen to be married to the vicious King of Ruskald for five years. Confined to his freezing city, forbidden to fight, Imogen sees nothing but darkness in her future - until the arrival of Elspeth North, heir to the Crown of Tremontane, brings three countries to the brink of war and sets Imogen free.

Now, sent to be the ambassador of her people to Tremontane, Imogen faces new challenges as she struggles to maintain her warrior's identity in a world of glittering ballrooms and foreign customs. As a diplomat, Imogen discovers skills she never knew she had - as well as a forbidden attraction to the handsome and charismatic King Jeffrey North. But when war once again threatens not only Tremontane but her own people, Imogen must decide: is she the warrior, the diplomat - or something greater?
