Ideally 300 pages or fewer but that's not a hard requirement.
I'd strongly prefer it be a standalone story instead of part of a series.
Fantasy / speculative fiction elements are completely fine (eg, ghosts, vampires, magic, etc), as long as it's still very much America in the Prohibition-era (and not, like, a fantasy world which happens to borrow a few aesthetics of it).
Any suggestions?
