Fiction must make sense. Even more then real life because the author has complete and total control of the world. You can get away with "and a miracle happened" maybe once depending on what kind of book you are writing.
I was the beta reader on a novel and I sent in a polite suggestion that he shift the location of home base of both the hero and villain, neither which were relevant to the current story, because it would cause trouble down the road. I got a "thank you for your suggestion, now GTH".
He is now in the second book of the series and is running into the problem I predicted.
Fiction readers are tough. Fans are even tougher.
The last fiction book I read was “The Eagle Has Landed”, back around 89 (when I was 35). I had read very few fiction books before that. My father in law liked to buy books at yard sales, but they mostly needed to be WW2 related (he was B24 gunner, DFC, and other awards; considered to have a superhuman aim by his own crewmates).
He rarely read fiction, but picked up TEHL at a sale, to compare it with movie he had seen years before. After reading it myself I had to agree his assessment: spending that much time reading something that is fiction is for other people, not me.
And romance novels? I’d rather rake leaves all day. (But then, my lovely wife has met my romance needs for almost 45 years.)
