Kissed by a Vampire. The Calling is Reborn Vampire Novels, #9

It's been two thousand years since a lover's betrayal stole her life and her hope... Vampire elder Stacia has been alone for millennia, chased by the memories of the night she had been turned into a creature of the night. Stacia yearns for love, but her nights are filled with only loneliness and quick bites to sustain her.  To escape the boredom and her aloneness, Stacia escapes to South Beach. But there she comes face-to-face with the handsome DEA agent whose life she had once saved with her vampire's kiss. DEA Agent Alex Garcia battles real-life demons every day, like the kind that are kidnapping women and selling them into slavery.
Determined to put an end to those crimes, Alex has to avoid the beautiful woman who can't possibly be what she says she is: a vampire. But when Stacia reveals what she really is to drive him away, Alex instead finds himself drawn ever closer to the complex woman who is courageous, passionate, and yearning for the love she lost so long ago..
