Book excerpt: Building on the success and importance of three previous volumes, Relational Psychoanalysis continues to expand and develop the relational turn. Under the keen editorship of Lewis Aron and Adrienne Harris, and comprised of the contributions of many of the leading voices in the relational world, Volume 5 carries on the legacy of this rich and diversified psychoanalytic approach by taking a fresh look at the progress in therapeutic process. Included here are chapters on transference and countertransference, engagement, dissociation and self-states, analytic impasses, privacy and disclosure, enactments, improvisation, development, and more. Thoughtful, capacious, and integrative, this new volume places the leading edge of relational thought close at hand, and pushes the boundaries of the relational turn that much closer to the horizon.
