Vampireville (Vampire Kisses 3) by Ellen Schreiber

Can Raven stop Dullsville from becoming Vampireville? For goth-girl Raven, dating her dream boyfriend is complicated, especially because Alexander's secret means they can only meet at night. And now they must be extra wary, with Alexander's archrival, Jagger, creeping around town. Then Jagger's exquisitely pale sister Luna also surfaces--and seems to have her sights on Raven's own longtime nemesis. Raven and Alexander must begin a terrifying hunt for Jagger and Luna's secret hideout. Can they drive them away before Dullsville is eternally threatened by these menaces from the Underworld?
