Query: This is a poorly written book!

The rating of 1-star for this book is rather a compliment for this poorly written book by Heidi Vernon. The book is outlined in a confusing manner with chapter content unrelated to it's chapter titles. Terminologies and definitions are not clearly defined. In fact, there ARE no definitions in this book. Since this textbook is written mostly in an essay form, students to this subject are expected to already know any terms or jargon in this subject. There are grammatical errors and typos in this book. THIS IS THE SIXTH EDITION? How did it ever get this far?
