Vampire Vengeance by Crystal Dawn

Darby Darknight was at a loss. Gertie was his fated mate, but so far all she’d done was make him the laughing stock of people he didn’t even know. His fault, he supposed, since he’d arrived after she had. Now he needed to get back her regard and claim her as a mate while they chased a vampire set on vengeance against his whole race. Easy, right?
Gertie Worthington wanted to be anywhere but here. Oh, it had been amusing at first. Darby had ended up on the wrong side of everything. Now it was so bad she felt sorry for him. That wasn’t good and he might use that to his advantage. All she wanted to do was go home.
