There’s more than one kind of synopsis. An Early Synopsis is a summary of your book that you write before you start. It can be as short as a paragraph or as long as a short story. My short story Oliver Troubles is close to the form of an early synopsis. If I’d spent more time with the idea, added relationships and a police investigation, it might have been a novella. You can make your early synopsis any length you’d like. It won’t be a true synopsis of your finished book. Your outline will change the story and writing the manuscript will change the story.
I’d like to walk quickly through the steps that lead to the true synopsis, also called the presentation synopsis, before talking about it.
