I will say that it does go into attachment theory, object relations theory and looks at things from a Freudian, Jungian and Kohutian perspective. What I find the most telling is the thorough case studies that she presents as to things that can and will go wrong in the therapeutic relationship. I can see from one particular case a lot of what went wrong between oldT and me.
Hope that helps. You can read some of the book on google books I think. That may give you a better idea.
