We’re at the tail end of our series on book proposals! So far we’ve talked about the five main parts of the book proposal - the Overview, the Author’s Bio, the Competitive Analysis, the Marketing Plan and the Chapter Summary. So, what do you need to know about choosing your sample chapter? Let’s get into it. First of all, it’s always a good idea to include your first chapter/introduction, as well as a later chapter. If you’re writing a self-help or guidebook, you want to make sure that one of the chapters is prescriptive – this is where you’re teaching them something, or detailing a particular step they need to take.
