I used to see where the story takes me but now I have tight deadlines, I’m much more organised. I usually write a synopsis first for my editor then plan the novel in Excel. Yep, Excel! Old work colleagues will tell you I used to HATE using Excel. But it’s a great tool for organising plots.
If you want me to send you a copy, email me. I also offer a service where I will read what you've written in your spreadsheet then offer you feedback and help, just email me if you need more details.
