When you compare the pace of the "substantial happenings" in your work to best-selling books, does yours hold up? Analyzing the structural language of a New York Times best seller can give you a whole new view of writing and how great stories are put together.
You can succeed in today's marketplace as an independent author. There's data to back that up. Of course, statistics and sales reports won't mean a thing if your book has not been professionally edited or if you rushed through the design process.
Discussions about structure tend to offer formulas, though formulas often lead to formulaic stories. But an understanding of narrative structure is important: you have to know the rules before you break them.
Your book's structure is the tool that will gather up your readers and keep them following along with you; it's the tie that binds all the parts of your story together, from end to end, and in the middle too.
