It’s different for every project for me. Books are a combination of character, plot, and setting. And every book I write, I could point out and say, oh, there was the first idea . Usually they’re growing separately , a couple ideas for the plot, a couple seeds for characters. An idea for a magic system or a governmental structure. Those will be growing independently in my notes file. I know I have a book when these different elements start to meld together in my brain, and change each other in interesting ways. I’ll start to say, all right, these two ideas belong together. Here’s this character who belongs in this plot. Is there a setting that I’ve been developing that also enhances this?
