Transition and Restart has found its format, which is the same as sayint that I've found a format. Last time I checked the story didn't write itself.
Frame, prologue, frame, chapter one, and then the coupling of frames and chapters until I have six chapters after which it's time for an epilogue.
And each chapter is around ten k words long and usually split into ten one k chunks with a POV-shift between chunks.
While on the long side for an LN I'm starting to see why anyone would run with a fixed format like this. No matter how hard it is for the reader to get into the story -- when you do you'll experience cadence of a kind.
Thus I've come to understand that the writer's contract with the reader can include scoping and narrative formatting.
