LemurKat, your deleted scene about the horror of war sounds like it would fit the theme wonderfully. And the practice of publishing deleted scenes or expanding short stories in an anthology into a novel of your own is standard. Bram Stoker published a deleted chapter from "Dracula" as a separate short story, "Dracula's Guest". The oldest story in my first anthology, "Best in Show" from Sofawolf Press in 2003 was "Rat's Reputation" by Michael H. Payne from FurVersion #16, May 1989, which was the oldest story worth reprinting from within furry fandom that I could find. (There were stories in earlier issues of FurVersion, but they're bad.) Payne has recently rewritten "Rat's Reputation" into a novel published by Sofawolf, with that short story as part of it but heavily revised. Watts Martin told me that the novelette "Tow" that he sent me for "The Furry Future" was an advance stand-alone prequel to a novel he's writing, for publication next year.
So send me your deleted scene. If it's chosen for publication, we can add a note in the Introduction or the About the Author that "this story is a deleted scene from LemurKat's forthcoming novel".
