As an expat in Denmark, I enjoyed reading this book, and definitely learned a lot from it.
However, to me it felt quite short, and sometimes I would prefer to get a deeper explanation about why this would be considered appropriate, and this -would not, instead of a short "Don't do X, do Y."
To me, this is a must-read book to people, who are planning/just started their expat journey in Denmark, but to a person, who lives here for a longer period of time - this book might not meet the expectations.
Also, I wish to see this book getting an updated version, as there are a lot of "unwritten rules" about how to give negative feedbacks, how to deal with toxic colleagues at work, what to do if you're the only English-speaking colleague, etc.
Overall, I wish I could get back in time and read it before moving to Denmark.
