Captive of the Falconstar. Falconstar Trilogy, #2

When freedom is a fantasy, only revenge is real. Sonya has lost her home, her name, and her freedom to the Hameji raiders who carried her off across the stars. Her only friend has remade herself as a Hameji queen-and now treats Sonya as just another pawn in her desperate game for power. Sonya tells herself that all she wants is to escape. But beneath that hope burns a hunger for revenge. When Lord Khasan takes a second bride to secure a powerful alliance, the women of the Falconstar are drawn into a ruthless contest to produce the firstborn son and heir.
As rival queens scheme for position and an old blood feud erupts into war, Sonya is pulled into a world where a woman's worth is measured by the sons she bears, the favors she can trade, and the secrets she can exploit. In the ruthless game of Hameji politics, captivity takes many forms. And if Sonya can survive the role she has been forced to play, she may finally have the chance to bring her captors to their knees.
