Have you ever evaluated how the beginning and ending of your manuscript are related? What about the beginning and ending of each chapter? Each scene?
Other than the obvious facts that these are related by plot and characters, consider the following comments from successful people in the industry:
"The opening image is also an opportunity to give us the starting point of the hero. It gives us a moment to see a "before" snapshot ... there will also be an "after" snapshot to show how things have changed. ... The opening and final images should be opposites ... showing a change so dramatic it documents the emotional upheaval ..." (Blake Snyder, SAVE THE CAT, pp. 72-73).
And, Donald Maass spends pages discussing the topic as well. "Does it matter what is the last line of your scene, or the first? Apparently, many authors do not think it does. ... That's a shame. Like a handshake, an opening and closing line can create impressions and expectations. They can set a tone. They can signal where we're going, or what we've done, or serve any number of other useful story purposes. ... Creating them deliberately, is a discipline worth developing. ... Suppose you did a first line / last line draft, doing nothing but honing the bookends of every scene in your manuscript. Would those little changes give your story a bigger and more effective shape?" (Donald Maass, THE FIRE IN FICTION, pp. 69-73).
What do you think?
Should every scene, chapter, and story have their "bookends" related in some fashion?
