Nancy McWilliams is the GOAT. She is where I would point anyone looking for a solid, digestible, sufficiently in-the-weeds grasp of contemporary psychoanalytic practice and theory. As an overview, you could do worse than just starting here. NM pulls in most of the central concepts in the course of laying out the process of meeting a new client and formulating an initial set of working hypotheses re: who they are and what they need. Her book Psychoanalytic Psychotherapy: A Practioner's Guide is probably the more natural place to start, but I don't know, this book is pretty solid.
Just at the level of prose and organization, I found it extremely impressive. Each chapter is 18-22 pages, and lays out one dimension of assessment in terms precise enough for the most punctilious reader, unpacking each with sufficient examples to draw out the idea and make it digestible enough for almost anyone. These chapters stack up one, two, three, up to 10 little lessons, plus a nice (20p of course!) summary. No chapter feels rushed or ungainly. You may want more, and in each chapter she provides recommended further readings for those who do. But no chapter is so spare that you could fail to get the idea.
Great book. Great writer. Nancy McWilliams writing in general has been the perfect bridge for me between philosophy and psychodynamic practice.
(PS One thing this is not is a history of psychoanalytic figures/concepts. For that, I really liked Mitchell and Black's FREUD AND BEYOND.)
