Blaze by Suzanne Roslyn

A dragon military romance in the sands of Arabia filled with forbidden love and dangers.
Gabi Pisano has been trapped in the Harrat clan compound for almost eight years tending to the women of the dragon alpha’s harem. It’s Adam Blaze’s sworn duty to bring Gabi back to her family, but when he makes an attempt to rescue her, Gabi puts his loyalty to the test and demands he helps rescue one of the alpha’s abused wives.
Rejected by his clan and now hunted by his own kind, Adam must return Gabi to her family by any means necessary. Gabi plays along with the charade of being Adam’s mate to cross the lava fields. Only when she discovers there might be more to this mate business then first thought, does she realize the danger she is truly in.
