An excellent question. Thank you. In fact a story develops on multiple planes. Research helps shape it, current events help shape it, what is going on in my own life helps shape it. Every day, all day long, choices are being made during the writing and editing process. Dead ends are pursued and rejected. Seemingly dead ends open up and reveal a passage to the next part of the story. Eventually the story has its own unique shape and structure because of the choices I’ve made during those months of work. After a year of trying to bring my thoughts, ideas, characters, plot, setting, etc. into focus, the book arrives on my editor’s desk and shortly thereafter returns to me with questions, concerns, suggestions. And the process begins again. It’s fascinating to think of how many different books could have emerged during this process, books that were not written, sacrificed to this one story line that managed to dominate all the myriad options available to me as I wrote.
