How to do a flashback without copying previous chapters from another book?
I have an idea for a related book that originates from a chapter in the current book. I want to include those scenes as a flashback but not sure how. They would become the second and third chapters in the new book if I included them. Should I just not worry about them being the same and copy them or should I try to change them? It would be a monster rewrite to do and still have them similar in both books.
