While the author's clinical experience seems extensive, this is not a book for those who have yet to decide whether Melanie Klein was on to something or not. The vignettes contain interpretations that are definitely in the realm of "through this lens I view the world". Clinicians of other persuasions can come up with interpretations just as valid as those offered by the author. There is no area of psychoanalytical work that requires such leaps of faith as dealing with preverbal individuals or very young children just learning to talk. This is a technical book for adherents to Kleinian theory or for students who are interested in a very lucid explanation of said theory.
