I read the preface to the English Edition during my second year of college and proceeded to read the entire thing during the next years. It's quite dense, and goes into detail on a few historical and uses economy lingo that can be complicated to understand, a lot of paragraphs I had to read again and again. However, the most interesting aspect of the book is the dialogue between Marxist theory and Foucaut that the two authors are able to draw, alognside a psychoanalisys of the neoliberal subject.
It's a book I usually always have on my table to go back to and reference. I highly recommend especially to people who are interested in Foucault.
