"The publication of this volume of papers from the Klein archive, together with critical discussion by notable Klein scholars, is a most exciting event.Every chapter is of interest, not only for its historical significance, but also because Klein’s clinical and theoretical thinking is further explored in the excellent commentaries and related to later developments in psychoanalysis. I recommend it most warmly. It forms an essential and impressive part of the array of recent books about Klein which attest to the continuing fertility of her legacy." --Margaret Rustin, Honorary Consultant Child Psychotherapist, Tavistock and Portman NHS Foundation Trust, co-author of Reading Klein
