I just finished listening a Writer's Digest on-demand workshop with Cheryl Klein of the Arthur A. Levine imprint at Scholastic Books. She shared a great deal of wisdom, and I was happy to hear her say that while writers are told "show don't tell," the truth is you need both. The workshop was on plot structure, and she's also a believer in the book map. Klein was also the continuity editor for the Harry Potter series, and so she shared this treat, J. K. Rowling's book/plot map.

I also found the image online here. Try Anita Nolan's article, "The End is Only the Beginning" for more about refining novel manuscripts. I enjoyed the workshop because Klein gets specific and practical.
