4. Make a (Very Flexible) Outline
"I am one of those people who likes to have a guide. It's a loose guide. (If you create a static plan at the beginning, you're sunk; the story is never what you think it is on day one). Due to the sweeping time frame and the voices moving back and forth, the outline for The Invention of Wings was the strangest one I've ever done. I created six large, separate outlines, one for each part of the book, and hung them around my study. I wrote them on big butcher paper that was probably 2 feet long, and I used pencil, because though I had a general idea of what would happen, I ended up changing it as I went. With pencil, you can always erase."
