A great question, simple but important, this came my way from a former student who is working on the first draft of her memoir. When you construct chapters, when you look at the book as a whole, you do have the option to give the reader small moments of pause, usually created with a few paragraph returns and white space (in chapters) or a couple of blank pages (in the larger book).
What are the rules around doing this? How often, and why?
Let's talk chapter breaks first.
