A bit late, but happy to rec.

Batman is, for a canon that has been around for so many years, a fandom where good gen fic is hard to find. Stories that explore romantic relationships are interesting, but the world that is Gotham city and its inhabitants is fascinating. Most of these stories won’t have a big mystery or action in them, but what they do have is a fantastic grasp of the characters, from caped crusaders to police officers to anonymous Gothamites.
