The scene-and-sequel structure that fixed my saggy middle chapters

Every early draft I wrote had the same problem reviewers flagged independently: a strong opening, a strong ending, and a middle that readers described as "fine" in the specific tone people use when they mean the opposite. It took a craft book from the 1960s to name what was missing: sequels.

The scene-and-sequel model splits every unit of story into two parts. The scene is the part writers naturally love: goal, conflict, disaster. The sequel is the part most beginning writers skip entirely: the character's emotional reaction to the disaster, a genuine dilemma about what to do next, and only then a decision that creates the next scene's goal.

My sagging middles were sagging because I was chaining scene directly into scene with no sequel between them — disaster after disaster with no processing, which reads as exhausting rather than tense, and gives readers no time to actually care about the stakes before the next one lands.

Adding even a paragraph of sequel — a character sitting with what just happened before acting again — was the single edit that got the most "couldn't put it down" feedback on my next draft, and it had nothing to do with adding more plot. It was adding room for the plot I already had to land.
