Or The Lost Boys...

Get her Dracula. You can't beat the real thing.
And if she can read French, the comic book serie Le Prince de la Nuit is the second best vampire story EVAR!!!1!

Talking about Dracula, there's this book called Carmilla, I think (at least it is about a lesbian vampire named Carmilla). As far as Wikipedia tells me, Dracula was inspired in it.

Has she read the House of Night series by P.C. Cast and Kristin Cast? That's a possibility. There's also the Nightworld series by L.J. Smith as well as the Vampire Diaries by the same author. You could consider the Sookie Stackhouse books by Charlaine Harris as well (the series True Blood is based on these books).
Kelly Armstrong and Laurell K. Hamilton are also popular authors that deal with the paranormal.
I've not read any of the above but we sell a ton of them in the bookstore where I work. I HAVE, however, read the Mortal Instruments trilogy by Cassandra Clare and I quite enjoyed it. Not vampire-centric, but there are vampires (and werewolves, and demons and warlocks, etc.) in it. Actually, I've read the first couple of Hamilton's Anita Blake, Vampire Hunter novels and they were fairly good. A buddy of mine loved them, but he says the later ones are not as good.

How about "Night Watch" (and it's sequels)
There are and [url=http://www.amazon.com/Night-Watch-Day-Two-Movie-Collection/dp/B000V6LSL8/ref=sr_1_5?ie=UTF8&qid=1249511265&sr=8-5]films.

Mmm... And what about some music by Theatres des Vampires inspired by Rice's books? :)

One of my favourite bands right now. Good call.

Thanks everyone for the advice. I think she'll enjoy what I got her =)

And it was??? Come on tell.

I second the revelation of the aforementioned birthday gifts!! Tell!

That's for me to know and for her to find out...*Hint* one of the books on this board and a little something she also likes I didn't mention.

I'll make the post that gave me the idea have a good rating.
