I have actually read many of the Culture Shock books, as I have lived in, traveled to, and/or reported to managers of several countries. I find it fascinating to learn about other cultures and nationalities, and so find the Culture Shock series indispensable. Although I have lived in Sweden, I realized that I knew little of the Finns and of Finland.
This book covers the level of detail that I would expect from a cultural overview, and it provides insight from other individuals beyond that of the author's. The previous Culture Shock book I had read was about Canada, and that one was terrible -- I did not feel that I knew much more about the country than when I had started reading. In contrast, the Finland edition is very detailed and engaging -- I have learned a lot. Perhaps it is simpler to write of a relatively small country with a population of less than 6 million as opposed to the 2nd largest in the world with great diversity, but nonetheless, I can attest that the Culture Shock! Finland guide would be a necessity for anyone contemplating a move to the country, or for someone who works for a Finnish company/manager.
