Outstanding summary of the major analyses of plot structure. Author Wijeratne begins with Aristotle's three-part story structure and goes in time order through various methods of systematizing plots to our current day.
What really makes this book interesting is how he applies the various plot structure theories to modern, popular works, like The Lord of the Rings, The Matrix, and Star Wars.
Writers familiar with 'The Hero's Journey' and 'Save the Cat' will find them both in here, as well as more esoteric approaches like the Japanese Keshokentetsu.
I recommend this book to any writer of stories.
