About the book: a year / A little less than a year ago I started a series of articles "Caucasus". And each of his publications was not ignored, for which I thank you very much. Over time, I decided to transform this series into a book. It very quickly outgrew the topic of the Caucasus alone, and this decision was quite logical. Moreover, it became possible to put together and systematize much of what had been written earlier. And today, finally, I present to your attention “RUBICON” - my new book. You had to wait a little longer than was promised, but nothing can be done: the work was delayed, the text arrays were processed, verified and assembled. Today this work is completed. Thank you all for waiting and I hope that I did not deceive your patience.
