I have been quite interested in the various methods of fiction story structure. Interested and confused. There’s the three act structure, the five act structure, the tent structure, the start with action – continue with tension to the critical climax and down the hill to close structure. I’m sure you know several more! Then there is the discussion regarding formula based stories.
I think you will find Rebecca Miller’s website a wonderful resource – here’s a link. https://rewriterewordrework.wordpress.com/ Do check out her post entitled “Novels in Three Acts…More or Less”. https://rewriterewordrework.wordpress.com/2017/04/08/novels-three-acts/
