Taming Him — Michelle M. Pillow

Driving alone one night, Maggie Stewart sees an alien spaceship and can't believe her eyes. When a gorgeous, hard-bodied stud named Vladei emerges and kidnaps Maggie, intoxicating her with his euphoric aura and chiseled features, she is utterly confused and tempted at the same time. Once she's aboard the ship, Vladei treats her like a queen, showering her with enticing pleasures and unrequited passion -- until she will do anything to be his.
