Great question.
Christian fiction (and perhaps all fiction) seems to go through stages. It seems that most fiction I read features cowboys, cafe owners, bookshop owners, or B&B owners. (And it’s almost always the owners, not the workers.)
I see a handful of accountants and a few marketing executives, but I don’t think I’ve ever seen a Human Resources manager or business analyst. I’ve never read a Christian novel featuring an auditor or an actuary. I’ve seen a few winery owners, but never seen a publican (which perhaps is less surprising than the winemakers.)
I see very few stories set in big businesses or government departments.
Even billionaire romances tend to feature heroes (and they are almost always heroes) who spend little of their time in the office. And when I see government employees, they tend to be law enforcement, teachers or medical professionals(because outisdethe USA,most medical professionals are government employees).
When I do see businesspeople, the story typically mentions their occupation, but everything happens outside this office. This does make sense: most businesses, especially large businesses have strict rules about relationships between colleagues.
So what occupations would I like to see?
Honestly, I’d like a good workplace romance where the woman is the boss or where the man is the one who sacrifices his career for love.
