I've had this idea in my head for ages, and I want to write it as a novel, just because I know I will really enjoy doing it. I know what the underlying theme is, what the story will be a metaphor for, and I know some people who would be great to base the characters on. But that's it really, I keep coming up with ideas for the actual plotline but none of them are right. I know what the "feeling" of the novel will be, I can feel the way I want the story to feel. But what do you do if the plotlines you come up with just aren't right? I've been thinking about this on and off for about 2 years and I really want to write it but the basic story just isn't happening the way I want it to. I don't know how to turn the underlying theme into a story basically. Does anyone have any tips?
