One of the last things you will write in your book is the introduction. Whether it’s a separate, distinct part or a component of the first chapter, you want to set the tone for the book and help readers know what to expect not only in information but also of you, the author. You are creating a relationship, without the benefit of physical movements or auditory tone of voice, so you must do that through your words. You are having a conversation and, having done your research, you’ve answered the questions readers would ask. You want to connect and converse, not talk at readers. If you welcome them into the subject from the start, they are more likely to stick with you and enjoy your work.
