My favorite book on writing nonfiction is Thinking Like Your Editor: How to Write Great Serious Nonfiction—and Get It Published by Susan Rabiner and Alfred Fortunato. One key concept they discuss in Chapter 2 is the importance of having a question that drives the book: "Every work of serious nonfiction begins with a question the author has about the topic and ends with an answer the author wants to provide." (p. 77) That question determines how interested editors and readers will be in the book.
I find that asking an overall question also focuses my writing. Knowing what question I'm trying to answer helps me decide how to structure the book and helps in making those many decisions about what to keep and what to leave out. For At Home in Her Tomb, my question was, What do the tombs and their artifacts tell us about life in ancient China?
Sometimes authors reveal in interviews, Author's Notes, or blogposts what question(s) inspired them to create their books. Here are a few examples:
To identify the question driving your own project, Rabiner and Fortunato recommend recalling what originally captured your interest in the subject "and why you find it compelling enough to write a book to answer it . . ." (p. 78).
What's the question driving your work-in-progress? Defining that question will help you research, write, and market your book.
