For anyone who read, downloaded, or is interested in reading, my English travelogue, 7 Islands, there is now an updated, corrected version of the text. The original was first written in 2017. No significant changes in content have been made, just improvements in style and focus (I still suffer from my years of speaking German in that my English sentences tend to be unreadably long–I hope this text is better in that regard).
The revised Portuguese text is now also available on the same page:
