I hope I can manage to explain myself properly here, but is giving your novel a particular setting, purely for the sake of it, acceptable? If a person wanted to write a fantasy novel, complete with jabberwockies, goblins, and all the other elements associated with the genre, a medieval setting would be justified, in the same way that Philip K Dick's 'Precrime' concept from his short story Minority Report, justifies a futuristic setting. But what if the plot doesn't justify the setting? Let's take a futuristic setting, for instance. What if the futuristic 'indicators' are there only to tell the reader the novel is set in the future? Example (stupidly simplified): A: England, present day. Mary took a deep breath and tried to hold back the tears. "I'm leaving you, John." As she turned to leave she paused and without looking back, added, "Who knows, maybe one day you'll win me back." She climbed behind the wheel of her car and drove away. B: America, 2076. Zina took a deep breath and tried to hold back the tears. "I'm leaving you, Trent." As she turned to leave she paused and without looking back, added, "Who knows, maybe one day you'll win me back." She hopped up onto the hovership and shot up into the sky. Okay, so let's imagine that is the entire story. There's no more. Is the futuristic setting here acceptable, given the plot offers no justification?
