I'm old. This is proven by the fact that every time I see a graphic novel/Japanese anime version of anything I think "Oh, look! It's (fill in the novel) as performed by the cast of Speed Racer!
Read the TokyoPop version of EllenSchreiber's Vampire Kisses, which is titled Blood Relatives. A lot of thought went into the art for this adaptation, and there is a bit at the back of the book about the process that is interesting. The story is the same, but reluctant readers will like the graphic novel version and perhaps be intrigued enough to try the other.
This is the main reason that I have also bought the graphic novel version of Stormbreaker and Artemis Fowl. They are good bridge books and do seem to interest students in reading the full text version.
The other proof that I am old-- do not get the whole vampire romance thing. Or goth culture. As I've said before, if students really want to be nonconformist, they'd find some tacky polyester clothing from the 70s. There are whole stores devoted to goth. It's just a different flavor of conformity.
