That is crazy fast! 40k words in 3 weeks! I’m excited to know you have more cozy mysteries on the way too. Your progress is inspiring to me; I hope I’ll find some writing success with continued push to practice. I’m curious how you lay out a general plot. So far my process is organic. I mull over snippets for weeks and see what bubbles up and kinda let the story elements grow. My plot for my NaNo WIP is loose. I’ll be a half-assing half-pantser!
So an idea for you: One month drafting. One month writing. One month editing/marketing/publishing. And one month rest. That’s a book every 4 months: one trilogy a year!
