Defiance — Beth D. Carter

Because of the rising tide of violence on a dying Earth, Jordan Kuper has lived fourteen years in the Berlin refugee camp, hiding her gender for her own protection. She knows how to fight and to take care of herself and her mother, but she is not prepared for the Xyran raider or human traitor who abduct her.

The Xyran Laith and the human David have a plan of vengeance, and it involves taking a human female to the sex market. They chose Jordan, but she is a hell-cat and doesn't take kindly to being abducted. She turns their lives upside down attempting to escape, even as they turn her assumptions about them upside down, too.

When they are forced to stop for repairs, Jordan finds a kidnapped Alphan girl, and everything changes. Now she has to get this little girl back to her parents, get herself back to Earth, and not fall in love with the two raiders who kidnapped her in the first place.
