Wikipedia aside, this book was my first real look at attachment theory and I'm glad that I started here. The book begins with a sufficiently detailed overview of Bowlby's life (for me), before moving on to summarise his theory of attachment and loss, including modern developments, criticisms and research around it.
I enjoyed this structure as it provided me with enough of a background and overview before moving into an in-depth examination of each aspect of the theory and it's implications in the worlds of psychoanalysis, psychotherapy, psychiatric disorder and society in general. Most sections have at least one brief case study which helps to flesh out and show the practical application of the theory. It was a thorough and scholarly review of both the man and the theory.
The author's psychiatric background comes through strongly in the unflinchingly medical manner in which he talks about mental health, and at times that was distracting, if not downright irritating (describing the narratives of people in severe distress as "rambling" doesn't sit very well with me). Additionally there were occasions where he produced controversial statements, such as "...with fathers who may be biologically unrelated to the children in their care, increasing the likelihood of insecurity or frank physical and sexual abuse" with no research to back it up, as if such things are self evident. I presume that is a relic of the period in which it was written and would be interested in reading an updated version of this book, noticing as I did after finishing it that it was published almost twenty years ago.
There were typos here and there, as well as oddly structured sentences throughout the book that jarred me out of the otherwise good flow of the writing.
Overall, though, this was a good book - well written (even if I did need my dictionary handy), well researched and managed to blend theory with practical application.
