Knight of a Trillion Stars by Dara Joy, (Matrix of Destiny Series, Book 1) from Books In Motion.com

If you get embarrassed easily, you'd better not read Knight of a Trillion Stars in a public place because you'll find yourself squealing with laughter. Deana Jones has had one of those days: she's just been fired, sat in something horrible on the train, can't get her car out of commuter gridlock, and has been soaked in a rainstorm. When she finally drips home, the strange alien waiting on her couch seems almost normal. Lorgan ta'al Krue claims he has been sent on a quest to sort out the cause of some mysterious time and space rifts. Because he is convinced that Deana is connected to them, he follows her to a science fiction convention. (The perfect date with an alien!) When Lorgan realizes the problems are originating on another planet, he whisks Deana with him, and she finds that although Lorgan may be her soul mate, he and his otherworldly ways take some getting used to. Don't miss the sequel, Rejar, which features Lorgan's sexy shape-changing brother.
