Part Two: Writing Convincing Nonfiction - Let's Begin Those Chapters

The nonfiction market is one of the toughest in publishing to crack. Having what you need to answer every question an agent and editor will ask of you is vital. In these two classes we will cover the essentials you need to “convince” the publishing professional you and your book are worth their time and investment. This course will cover the 5 basic book structures—introduce , test and organize your material—build your outline—define your target reader—and describe the skill or ability the reader will learn or the problem you will help the reader solve. *We recommend taking Part 1: Writing Convincing Nonfiction: Idea to Outline as a prerequisite.
