A lifetime ago, I took a writing course taught by Al Dewlen. I've probably forgotten most of what he had to say, but a few things stuck with me, and one of those was something that (I believe) he called "rolled paragraphs." The idea is that you write a normal paragraph in the style your fourth grade teacher taught you (a subject sentence, a middle sentence or sentences, and a concluding sentence), and then you mess it up. Normal paragraphs: 1. Introduction. 2. Stuff. 3. Conclusion. 1. Introduction. 2. Stuff. 3. Conclusion. Rolled paragraphs: 1. Introduction. 2. Stuff. 3. Conclusion. 4. Introduction. 1. Stuff. 2. Conclusion. 3. Introduction. The idea is that you then end up with a reader who, having finished a paragraph (and reached what should be a good stopping point), is now left wondering where you're going--since, of course, you already left. The intent is to make a book emotionally difficult to put down. Like, literally. And of course the same concept works at higher organizational levels like scenes, chapters, and so forth. This is one of those pieces of advice that I actually try to follow. (There aren't many--just ask anyone who's met me.) I find that it's difficult to do where you have a lot of dialog, but I think the existence of a line of dialog on the very next line pretty much makes it unnecessary, so whatever. The big reason I try to follow it is that, in my experience, it's almost disturbingly effective. Like mind control. What was the last book you read that you couldn't put down? Why do you think that is?
