Wolfgang by Grae Bryan

Wolfgang Volker is many things: vampire, psychopath, connoisseur of fine living. But impulsive? Never that. Until the day he sets foot in Hyde Park and catches a certain enticing scent on the wind. His mate is here, gorgeous and oblivious and undeniably human. And it doesn’t take long for Wolfe to make the most impulsive move of his whole undead existence.
Dr. Eric Monroe has plenty going for him: he’s good-looking, he’s a doctor, he’s… well, that’s kind of it. And true, the citizens of Hyde Park think he’s a sleaze and a dud and make sure to let him know it. And no, he doesn’t have any real friends or family members who don’t drive him up the wall. But that’s fine, right? Until the day his standing massage appointment ends not with a tip, but with a bite.
Now Eric has to navigate a new world, a new existence, a new, very particular diet. All while coming to terms with the strange, obsessive, all-too-alluring vampire who claims they’re destined mates. But what does it mean to be mated to someone who’s never truly cared for another person before? And can Wolfe convince Eric to stick around long enough to find out?
