If you’re looking for an erotic vampire story with a gay twist then J.R. Ward’s ‘Black Dagger Brotherhood’ series are the ones to look out for. ‘Lover at Last’ is the 11th book in the series but works well as a standalone also.
The story follows the stories of Qhuinn, a disavowed aristocrat who is now a brutal fighter in the darker corners of a ravaged New York and Blay, who after years of unrequited for Qhuinn has finally started to move on. What follows is a multi layered story with good dramatic tension and erotic scenes. If you like Twilight but just wish there’d been more male on male action then this series is for you.
