Vampire, Interrupted

In over 700 years of existence, Marguerite Argeneau has never held a job. Her fledgling career as a PI seemed like such a simple plan - track down Christian Notte's father and convince him to give up the name of his son's mother. But, the best laid plans. . . Julius Notte has loved Marguerite for a long time - a very long time.
When she turns up on his doorstep, demanding answers to very sensitive questions, it's clear that something is wrong. Certain he's the only one who can save her, Julian is determined to rekindle their love. But, someone is standing in their way; someone who will stop at nothing - not even murder - to ensure that Marguerite's past stays in the past

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.
