While this is a good resource book to sit on the shelf, it is not an interesting, insightful, or enjoyable read. It is one of the most boring textbooks I have ever had to read. My professor was right: I will use this when I am a practitioner, but as a student, it is tough to get through. There are MANY, MANY spelling mistakes. Whoever edited this book should be ashamed. I can't wait until I am done this class so i never have to read through the book again. STUDENT TIP: Don't bother reading each chapter in its entirety; only read the summaries at the end of each chapter.
