What is a Scene?

It sounds like a simple question. But if you hand a book over to two editors, they will probably define the scenes of the book in very different ways. Even I have arguments with myself, both sides winning, of where a scene starts and ends. That is because a well structured book is constructed with building blocks of action and reaction, from the smallest kernel of bickering dialogue to the large scale relationship between the story’s inciting incident and climax.

And the most digestible of these blocks are scenes.
