The defiant one

The beloved one

I hope that this is it

Lynsay Sands - Vampires Are Forever
Summary:

Inez Urso is beginning to have her doubts. Her business associate Thomas Argeneau has some interesting traits, like an allergic reaction to the sun, excellent night vision, and not much of an appetite for food. And to top it all off, he just tried to bite her neck . . . but maybe that was a sign of passion. If so, she'd be happy to experience more, despite her determination not to mix business with pleasure.

Well, if not forever, at least two hundred years. Inez is the most beautiful woman he's seen in centuries. Those luscious lips, seductive curves, and her elegant neck . . . he just couldn't resist the temptation of one little bite. Now Thomas will do anything to convince her that only an immortal like him can satisfy her all night long . . .

Lynsay Sands

After seven hundred years of life, Marguerite Argeneau finally has a career. Well, the start of one, anyway. She's training to be a private investigator, and her first assignment is to find an immortal's mother. It seemed simple enough, until Marguerite wakes up one evening to find herself at the wrong end of a sword. Now she realizes she's in way over her head.

Julius Notte wants to protect Marguerite, and not because someone just tried to take her head off. She doesn't know it yet, but she's his lifemate and he's determined to woo her. It's been over five hundred years since he last courted a woman, but surely the techniques haven't changed. Now if only he can keep her alive—so to speak—so they can have that happily-ever-after.
