I read the Save the Cat! Writes a Novel book a few years ago. I liked it because it approached story in a very logical way, which appeals to me as an outliner. It works like The Hero's Journey and many others--it takes the major story twists and turns and lays them out in a flexible pattern. You do not want to use this as a formula, or your story will become stilted. Many people argue against using "formulas" such as these but these guides are merely a tool and any tool used incorrectly can be bad. Used correctly this book can be very helpful, especially for new writers. When I first started writing short stories I used a tool like this to guide my plot and keep the story tight. After a few dozen stories, it became ingrained in me and I don't need to use that guide as much.
