What do people think of the idea of a novel about scientifically plausible vampires?
I'm talking humanoid - externally indistinguishable, or very nearly - creatures, though mentally, emotionally and culturally very different. Immortal blood-drinkers that reproduce by turning humans into vampires. Based on more-or-less theoretically plausible science: I don't claim it to be absolutely adamantine, but firm enough to stand on, with care.
I welcome all thoughts and comments.
