Dark Lover by J.R. Ward
Sexy vampires will always be trendy, in our opinion. Dark Lover, the first book in a multiple-book series by J.R. Ward, introduces the Black Dagger Brotherhood, a group of warrior vampires who protect others from those who hunt them. When Darius, a fellow "Brother" is killed, Wrath, the leader of the Brotherhood, is tasked with taking care of his daughter and making sure she's able to transition into a full-fledged vampire. But the older she gets, the more the sexual tension between them grows until it implodes in the pages.
