Venom: Antiserum Part III (The Antiserum Novels)

Jocelyn is finally living the life she's wanted ever since she became a vampire - alone and unbothered. Nothing stops her from getting her fill of blood, she has friends who accept her and her addiction, and she's starting to find some sort of normalcy after being kidnapped, falling madly in love, and then having her heart shattered into a million pieces. Thankfully, college has been keeping her mind busy whenever she's not satisfying her thirst... until Keith comes along. She doesn't have time for humans but this one always seems to claim her attention, and her heartstrings. But vampires are beginning to drop like flies around her... The Others have come up with a new concoction thanks to Nikki's betrayal and in order to stop it, she has to come together with her twin, Vasile, Sadie, and Adrian, in order to really live peacefully. If only that was easier for her to do.
