His Human Captive by Evey Embers

Tabby hates that she has lost control of her life. Living in a world where the brutish alien overlords decide her every move, she lashes out and rebels at every opportunity. But, it is precisely this insubordinate attitude which gets her into a mess of trouble. After committing her final offense, she is punished to 10 years of servitude at the hands of her new master…
SHON is as intimidating and harsh as he is handsome – yet, something about the alien master captures Tabby’s imagination and sets her loins on fire! Still, she is not one to be ordered around and so her stubborn behavior persists.
That is when Shon exposes her to a whole new world of pain and pleasure… rough things she has never experienced before. Their relationship only grows hotter and hotter until an outside force threatens to destroy any happiness they may have created. Shon must decide if he loves this human girl far more than he even loves himself…
