I'm disturbed, not so much by you telling us this, but because it seems you've really thought it out. Ew. ;)
Either way, you don't pull a lot of punches in your descriptiveness, do you? But I'm not terribly surprised, since I've read a lot of your work already (Necromancer, Death Song, Eternal, Ground Zero, Innkeeper) and probably going to read them all. Or, at least, try to. ;)
I agree with the sparkling vampires. Unless they're wearing a TON of diamonds, or putting mundane glitter glue on them, they really shouldn't be so...damned shiny. I'm fine with the fighting their own nature too, but you do make a good point about WHO they tend to fall in love with romantically.
But, I do have to say something good about the Twilight series. After reading it, my hopes of ever being published took on a new light. If THAT can pass, well, perhaps something I write can also. ;)
