I have a 500 word fic that is in dialogue. I have never tried that approach before, and I could use some feedback. I won't bother to post any of it here, since it is so short and, being dialogue, the "hook" is spaced out over several lines of speech. The gist is someone who goes on a blind date, discovers that their date is a vampire, and then gets cornered with their undead date in a blind alley by an angry werewolf. The story picks up from there.
