Definition: what is a nonfiction book coach?
A nonfiction book coach is a guide who helps an author plan, write, and finish a true, useful book. The coach does not write the book for you, which is what a ghostwriter does, and does not only polish a finished manuscript, which is what an editor does. Instead, the coach works during the writing: clarifying who the book is for, shaping the outline, setting a pace, and giving feedback so the draft keeps moving.
At Defining Moments Press, book coaching is part of the Author Training program, which pairs one year of coaching with an 8-week course to write the book, then formatting, book design, marketing, and a full launch. For professionals, the point is not only the book. As Defining Moments Press puts it, it is about what the book does for you.
