She's My Eternity by Valerie Hunter

The only thing she hasn’t managed in a thousand years? A long-term girlfriend.

After moving to New York City to help Sylvia and Aster adjust to unexpected parenthood, Yasmine is pushed back onto VampireMatch—where a dozen disappointing dates convince her that another thousand years alone might be her fate.

That is, until she meets someone she absolutely cannot fall in love with: the devastatingly beautiful, and devastatingly human barista, Bella Dragomir.

But as a string of vampiric killings begins spreading across New York City—killings that seem to draw closer and closer to Bella herself—Yasmine finds herself wondering if the truth is more complicated than she wants to believe. Especially when it comes to Bella.
