I think it can be pretty much guaranteed that no fantasy novel is going to thrive when it is marketed as “labor and industrial relations.” Certainly my Thunder King didn’t.
No one was able to tell me how my fantasy novel wound up as labor and industrial relations. Nothing in it about collective bargaining, overtime, or automation. Like a book by some guy that no one ever heard of doesn’t have enough trouble finding buyers.
I just checked. The Thunder King is not exactly burning up the track today, but it is doing much better than it was as “labor & industrial relations.”
