Here's one explanation:
In step one, the writer comes up with a one-sentence description of the novel.
Step two expands the short description to a paragraph of description.
In step three, the writer does a one-page summary sheet for each main character that reviews that character’s major goals, conflict, motivation and epiphany and summarises the story from the point of view of that character.
Step four returns to the plot and involves creating a brief synopsis. This time, the writer takes those five sentences from the summarizing paragraph and expands each one into a paragraph of its own.
