A short story by science fiction writer William Barton. Living in an obscure corner of the Silvergirl Universe, lovers Desmond and Molly are something very old, or perhaps something very new. It's hard to say. Perhaps they're vampires, or incubus and sucubus working as a team. Perhaps they're something else entirely, but whatever they are, in they end you'll know them well. Maybe you always have, if only in some nightmare from which you were glad to awaken.
