Here's what a book outline is, the structures to start from, and how to turn it into a draft.
What is a book outline?
A book outline is the plan of your book: its chapters, in order, with what each one does.
It turns a big project into pieces you can write one at a time.
Structures to start from
Every structure here is a known way to shape a book, credited to who made it popular:
| Structure | Best for | Parts |
|---|---|---|
| Build as you read | How-to nonfiction | 6 |
| Problem to promise | Self-help and business | 8 |
| One big idea | Idea-led nonfiction | 7 |
| Memoir arc | Memoir | 7 |
| Three acts | Any novel | 8 |
| The hero's journey (Christopher Vogler) | Adventure and fantasy | 12 |
| Seven points (Dan Wells) | Plot-driven fiction | 7 |
| 15 beats (Blake Snyder, Save the Cat!) | Commercial fiction | 15 |
My own AI OS book uses the first one: every chapter ends with the reader's system a little further along.

Questions about outlining a book? Here's what to know.
A book outline is the plan of a book: its chapters in order, with what each one does for the reader or the story.
To outline a nonfiction book, start from a structure like problem to promise or build as you read, give each chapter one job, and set a word target so the chapters add up to the book.
