Je vais faire mon commentaire en anglais:
A good book, with very interesting ideas about truma; for example the concepts of "noyau chaud" et "noyau froid" - particularly, I dont thing that these choice of words are the best ones to name this concepts - that adds to the comprehension of the questions discussed in the book. A especial part of the book, however, deserves a comment: there is a great introduction by Claude Le Guen. The book is an important brick in the wall of studies about Ferenczi and trauma. Some of the ideas - I'll repeat - should be more discussed and made known in C. Janin's following papers or books.
I recommend.
