This work by Steiner has much in common with the theories outlined in Rosenfield's work in 'Impasse and Interpretation'. Both deal with apparently 'stuck' patients in psychotherapeutic treatment and both explore the aspects of the mental structures leading to this 'stuckness'. I have found this book invaluable in work with personality disordered (especially narcissistic) individuals, as well as in a broad range of other disorders.
This is a fascinating discourse on the notion of the internal world that subsumes consciousness at times of great stress; a sort of traumatised never never land that often replaces reality for the most emotionally disturbed and damaged individuals in society. However this book wants to help us understand this process normatively, and so be better able to accept and work therapeutically with its defensive pragmatism rather than label it simply as abnormal phenomena, and in this it suceeds very well. I highly recommend this book for anyone working in mental health
