There's an interesting piece over at B&N on the staying power of vampire fiction, I Vant to Suck Your Blood
It always fascinates me that the writers in SF & F (and sometimes horror) seem to have such disdain for vampire fiction (if they're not writing it themselves).
As you know, I love a good vampire novel (I've sold at least 200, and bought another 25 at RR). I believe you can never be too rich or too thin, or have too many vampire novels.
I'm reading the manuscript of WOMEN OF THE BITE edited by Cecilia Tan right now, and it just amazes me how fluid (pardon the pun there) the vampire mythos is.
