I have been to south america many times, as it is my prefered continent. Once for 6 months travelling nearly all countries, but since then several times back to some of those.
I think the writing style and the background stories are very good. It did not reveal that many new things to me, but it named impressions I had, and made me think a lot. I read through this book in only 2 days, and enjoyed it very well.
Make no mistake - this is not a typical travel book. Although light, it does not cover the writer's journey to the highlights of the continent. It depicts the backgrounds of the nations and the people. I do not agree with everything he writes, but that is a minor detail. I think it is pretty accurate. For each theme the author focusses on a different country, but the reader should realise many of the themes also play an important role in the other countries.
There are a few pasages in chapters that are less interesting, but on the whole, this deserves a 5 star. I have read several other books on south america, and it is one of the best !
