This book is about a journey along the longest national border of the world, carried out between 2011 and the end of 2015. It spans over 60,000 km and shares land borders with Norway, Finland, Estonia, Latvia, Lithuania, Poland, Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia, and North Korea. Japan and USA both share sea borders with Russia and are just a short sea trip away. In the South, Russia also borders with Abkhazia, a partially recognised state located on the beautiful coast of the Black Sea, previously a popular resort destination, a Soviet Riviera. From warm regions of the Caucasus, the project takes us to the extreme cold in the North, as a Russian temporary ice base Barneo, drifting in the Arctic Ocean close to the North Pole, is also included in the series. In her rigorous project, Maria Gruzdeva united all these different geographical locations under one comprehensive study of the Russian border.
