Wow, a lot of people are liking 'Best Friends'...thank you. I wasn't prepared for the reception this would get, and to see so many add it to their Library just...wow.
I do outline, basic - one sentence of what the chapter is about. Chapter 3 is in progress...sort of. What happens there feeds into chapter 5 - so guess which one I'm currently working on... (sighs)
At least with the software I use, it's easy to go back and forth. If you haven't looked at Scrivener - do so, it's a great application.
