On any given page, sometimes in any given paragraph I'll have one question and sometimes more. They range from details of Assyrian armor to women's hairstyles from the period. I don't expect (or need) to answer every question, but I'm looking forward to learning more about my characters' world.
I plan to work through the novel and gather information, make lots of notes and photocopies and bring the data home from my week at the library. The integration of that information? That will take place at home over many weeks, probably months. I once said I never expected to write a memoir. I never expected to write an historical novel, either! This will be a very different way to revise for me. I'm looking forward to it.
More on how that works as it unfolds.
