Klava Mylva, Empress of twenty countries, ruler of the Kavkan elite, is forced to torture herself and her two Bloodsworn sisters every day for the past thirty-five years. For they are to act as one, be one, even unto death. At their yearly gathering where they tear their flesh to match each other perfectly and meld memories from their year of separation, they learn of a threat. An unknown kingdom threatens, but it's too late. They're already there.

Ryven has dreamed of a peaceful world. Where no child is orphaned with the ugliness of war. Together with his parents and siblings, he plans to make it a reality. But first, he must subdue the powerful mercenary Empress with fire in her veins. The more he reads about her, and then studies her once he infiltrates her country of Kavkan, the more he respects her. Watching barbaric traditions torture her, he vows to help her break those bonds and set her free. With each day, he finds his respect marches alongside desire. It's made even worse when he made his move to take her country, and kidnap her. Now, he has to convince her not to kill him.

Together, they could rule the world, but can they keep their hands to themselves long enough to reign?
