For what it's worth, I appreciated the book as "advanced" in comparison to all other techniques books out there, which are quite basic (I'm thinking Ed Jacobs' Creative Counseling Techniques). No other book even delves into much of the content in this book, such as the Jungian and CBT concepts, and outside of a Joseph Campbell book, I have not encountered anything that suggests even deals with metaphors, let alone use of them in therapy.
While I agree that the concepts may be covered in a basic first-year master's-level theories course, they have yet to be incorporated into any sort of summary book beyond that very class. In essence, once a student graduates with his theory, he probably will never see this stuff again so it makes for a nice reminder. Also, the concepts may be basic but a well-integrated therapist can use the techniques presented in this book because although they are rooted in their theories of origin, they are largely atheoretical and thus can be used effectively regardless of orientation. For instance, I consider myself to be primarily a reality therapist yet I frequently utilize REBT and analytic psychology because my clients can grasp it. This book provides an effective example as to how I can go about doing that.
In summation, I do not believe that the title is "way way off" simply because no other book claims to offer advanced techniques. I supposed when a trout is the only fish in the pond, it can call itself a shark until a real shark comes along (see, there's a metaphor!).
