Unwilling Mate by Opal Carew

Eva vowed never to surrender control to a man again, but now she is held prisoner by an alien who insists she belongs to him.

Eva learned the hard way never to trust a man. Even when they claim everlasting love, it’s all a lie. A free luxury resort vacation is just the ticket to forget her broken dreams and all the pain her ex has caused her.
But after she steps into a VIP elevator, she winds up aboard a spaceship loaded with drop-dead gorgeous aliens too tempting to resist. Especially Commander Larson Raa-ling who claims to be her soul-mate. But resist him she will.
Larson knows Eva feels the same potent desire he feels for her, but her fear and stubbornness are holding her back. He knows he must be patient to win her trust, but constraining the gut-wrenching need to join with her is sheer torture. The longer she resists their bond, the closer to the breaking point he comes.

Eva tries desperately to remember all the reasons she vowed never to surrender control to a man again. But as Larson chips away at her defenses, her resistance is crumbling by the second.
