Ache by R. E. Butler

Two-hundred-year-old vampire Bellamin wants nothing more than to find his beloved mate, and he holds out hope that he’ll be the first vampire to ever feed from her. When he scents his mate in the club one night, he’s disappointed when he realizes she’s paid food for the members of the coven but decides he doesn’t care about her past.
Kelly Archer doesn’t consider herself impulsive, but when her sister Selma is in danger of losing her job as paid food at the vampire club and begs Kelly to take her place, she decides to do something entirely out of character. Donning her sister’s revealing clothing, Kelly ventures to the club and is almost through her shift when she meets Bellamin.

Bellamin knows she’s his beloved, but his prejudice and Kelly’s fraud threatens to tear their budding romance apart. And the moment he gets back into her good graces, an old enemy appears.
Kelly’s no average human, and when the uniqueness of her family history is exposed, Bellamin must keep her safe. But can he keep her by his side forever?
