When you saw that title what did you imagine? A scene from Alice through the Looking Glass?

One of those high speed reverse sequences in a magical fantasy film, when everything rewinds? Or perhaps a time-slip scenario?
Or simply an image of mirror writing?

Would it be wonderful if we could indeed start at the end and then proceed to the beginning? Or would it rather be a nightmare? Of course, TS Eliot encapsulated this idea when he wrote: The end of all our exploring will be to arrive where we started and know the place for the first time.
In one of the chapters of my book Perilous Path I looked at the seemingly paradoxical idea of writing a book in reverse. In many ways this idea appeals to me. After all, when we consider the obstacles a writer confronts during the creation of a novel, it seems that all the problems are wrapped up in the tyranny of time. The journey of a novel is often about getting to know your characters and allowing them to reveal to us what we’re writing about.
Robert McKee in his excellent book Story says every story has a controlling idea; and the controlling idea is embedded in the final climax of the story. In fiction, controlling ideas are below the surface. So in one sense the process of writing a story does indeed involve travelling backwards, on an unconscious level. You will find more about this in my chapters in Perilous Path inspired by the theories of Carl Jung.
Our controlling idea, I believe, may not necessarily be fully worked out on a conscious level. It is hidden deep in the unconscious and the act of writing a work of fiction may simply be the working out of this, and the process of bringing it to the surface, and out into the light. Thus on an unconscious level we do indeed write backwards.
Some novelists start a first draft with their characters, and begin telling the story, and go where their characters take them. Finally the controlling idea is revealed. Then we might say they go into reverse, moving back again, and imposing structure in subsequent drafts. Others plan the novel out in detail using the 3-act structure, plotting out the story points before they begin writing. Perhaps, for them, the controlling idea is already out in the light and clearly defined.
Examples of controlling ideas include: ‘Goodness triumphs when we outwit evil’ (The Witches of Eastwick by John Updike). ‘Justice prevails when an everyman victim is more clever than the criminals.’ (The Firm by John Grisham).’To love with integrity requires personal worldview transformation’ (Pride and Prejudice by Jane Austen). Here are some very helpful blogs upon the subject of The Controlling Idea by Shawn Coyne and Steven Pressfield.
