This book is absolutely amazing to read for any TCK, or a person "who has spent a significant part of his or her developmental years outside the parents' culture" ("The TCK profile" seminar material, Interaction, Inc, 1981, 1). At first reading the book had been very difficult simply because I was crying so much reading it that I could not even see the letters anymore. This is because that book puts into words what many TCK knew unconsciously but never put words on it, like the feeling of being different and awkward in one own culture, not having a sense of where home is, etc...
The book has a very positive approach to the analysis of TCKs, and will refer to these issues as challenges rather than problems, and gives keys to transform these challenges into useful tools for everyday life. It also outline well the advantages one gains from such an experience, and it will probably help people maximise the use of these particular skills in their life.
It also gives advice about moving abroad by explaining the different emotional steps a person goes through when moving to a new country, and how to deal with relationship issues related to the TCK way of life and many other useful advices.
In addition, it has a great section on what relatives and friends can do to help the TCK with eventual problems that may arise from that particular experience.
I really recommend this book particularly for adult TCKs as it will help them put in words what has been in their heart all along.
