Exiled... Book 7 in the Brides of the Kindred Series. The Brides of the Kindred, #7

She was never meant to command him. He was never supposed to kneel. But on a world built on dominance and submission, pretending may be the one thing that sets them both free. Lissa and Saber were never supposed to fall in love. Both are Touch Kindred, and by the harsh laws of their people, that alone is enough to keep them apart forever. No matter how much Lissa aches for Saber-or how much the proud warrior clearly wants her in return-they can never openly claim each other.
Then fate sends them to Yonnie Six. To recover stolen scrolls on the barbaric pleasure-slave planet, Lissa must pose as a cruel Mistress and Saber as her obedient slave. It should be simple: play the roles, complete the mission, and walk away. But nothing about Yonnie Six is simple. Not when Saber is so willing to kneel. Not when Lissa discovers a side of herself she never expected. And not when every command, every act of service, and every forbidden touch pushes them closer to surrendering to the desire they've both tried so hard to deny.
Because on a planet ruled by domination and submission, pretending to own the male she loves may awaken a hunger Lissa can no longer hide. And once Saber belongs to her in every way that matters, letting him go may be impossible. Exiled is the very first book set on Yonnie Six, a planet ruled over exclusively by women. The Yonnites believe that men are only fit to serve and pleasure the woman who owns them.
And Saber is *very* willing to serve and pleasure Lissa. There are 31 books in the main Brides of the Kindred series and more on the way...
