I used to write vampires. A lot. I got deep into it all, did research, read everything I could get my hands on.

Which Vampire stuck out for me?

None of them. All of them.
Even Vamps have the good, the bad and the downright horrible. There’s Sebastian, in Michelle Hauf’s Dark Rapture. The musician… and, oh, he’s SUCH a fiend! He’s not nice. Not really. I love him to bits. :)
There are the vampires in J.C. Wilder’s series. Damn, I loved them. I really did.
There’s Nosferatu. Now, that fiend couldn’t be called romantic or nice, or sexy by any stretch of the imagination — but I still like him.
Laurell K. Hamilton’s Jean-Claude… I will never forget that bathroom scene. But alas, here is a writer who has gone too far for my tastes. I used to read everything she put out — then I read Narcissus in Chains (I was already apprehensive after the previous one) and that was the end of it for me. I just couldn’t get into it anymore. Where earlier there had been sexual tension, we now had the other extremes which looked too much like orgies. It turned me off an otherwise very well written series.
Silhoutte Nocturne has a series within the series — Bewitching the Dark — which puts a great slant on what hurts a vampire.
Kreseley Cole’s Vamps are kinda cool too, but her books span so much more than just vampires.

There are a lot of facets to Vampires, I haven’t really found one I didn’t like and I can’t wait what others will develop. I don’t really have a favorite, other than I like them dark and a bit nasty. Vampires shouldn’t be nice. They should have an agenda. They are predators after all. It’s a bit like taming a wild beast, with a bloodsucking evil minion from Hell being possibly the most dangerous of all the beasts you could try to tame. It might just end deadly. :)

But if I absolutely have to pick one… At the moment it would be Michelle Hauf’s Nikolaus Drake, who got suckered when he drinks from a witch who got drenched in a love potion. The whole concept made me giggle, and watching a lovesick vampire try to romance a witch who’d rather kill him… oh my. LOL.
