J. K. Rowling's Plot or Book Map
for Book Five, Harry Potter and the Order of the Phoenix
Scholastic Books Editor Cheryl Klein (Arthur A. Levine imprint) presented in a Writer's Digest University on-demand workshop. I found a larger copy of the image online.
Klein also recommended reading Anita Nolan's article on refining your novel manuscript, "The End is Only the Beginning." Klein was a continuity editor for the American editions of the Harry Potter series.
Watch Rowling explain how her
book map or book grid works for her at The Leaky Cauldron.
