I'm not sure specifically as I haven't read this particular series in detail. But typically in vampire novels, there's often a central vampire character who is either the protagonist or antagonist. There might also be a human character who gets involved with the vampire world, perhaps a love interest or a detective - type figure trying to figure out the vampire secrets.
Well, a significant theme is the exploration of the 'otherness'. The supernatural characters in 'Dead Until Dark' are different from the ordinary, and the novels look at how society views and reacts to them. Also, there's the theme of survival, both for the humans in a world with dangerous supernaturals and for the supernaturals themselves who might be hunted or persecuted.

Also, the setting of the novels could be very atmospheric, creating a spooky and alluring world for the vampires to inhabit.
One popular 'Dead Until Dark' - type vampire romance book is 'Twilight' by Stephenie Meyer. It tells the story of Bella Swan and Edward Cullen, a vampire. Their love is forbidden yet intense. Another is 'Interview with the Vampire' by Anne Rice. It's a classic that delves deep into the vampire lore and the relationships they form. There's also 'The Vampire Diaries' series by L. J. Smith which is full of love triangles and vampire drama.

Love and relationships are also important themes. Sookie has various romantic involvements, especially with the vampire Bill. These relationships are complicated by the different natures of the characters, like the fact that Bill is a vampire and has different values and needs compared to Sookie as a human.
