I'd query for what purpose you need to categorize. Genre is a tricky one to bludgeon stories into a single select. Flexible approach would be a multi-select on the Genre field (Horror and Thriller). Tag field also Multi-select Campfire, Paranormal, Forest etc etc and make use of the filter "contains" to avoid too many tags. If you absolutely need a single select then name that field with the reason why e.g "Website Genre" if you don't want the story appearing twice in an automatic feed.
With all stories in one table, it could be easier to organise to your workflow instead - Group records by Status field (Idea, Writing, Editing, Final) or Pub Status "Published, Unpublished" or set up a view on the Pub Date field to ensure you're setting content across the year. etc etc. Easier to set your data on clear fields. Genre is a subjective field that can muddle.
