Back in 2001, before there was a Twilight series, there was another set of vampire books, this one focusing on blood suckers in the deep south. Since Stephanie Meyer hadn’t yet ruined the genre, this series focused on the things vampires ought to do, have sex with people and drink their blood.
Dead Until Dark is the first book in that series, and bloody sex is pretty much the only thing that happens. Vampires drink people blood, people drink vampire blood, vampires drink Japanese bottled blood, and everybody has sex with everybody else. All the while, there is a serial killer running around murdering waitresses. It’s like a classic whodunit, if nobody really cared who dun it, but instead focused on fucking and exsanguinating each other.
