I'm disappointed with this read, it's full of superficial, unjust Soviet era-inspired framing of the North of the region and the history of its people.
For instance, the author denies the Circassian struggle (perhaps the longest resistance in the region, documented by historians from various parts of the world), and claims the natives left at the beginning of the war, arguing that they already "surrendered" two centuries earlier (two centuries before the Tsarist invasion of the Caucasus even started), when Tsar Ivan I married a Circassian noblewomen, Maria Temryukovna (I wonder, were they able to see the future?).
Moreover, the author addresses Kabardians, Cherkess, and Adygs as three different but "related" groups (a narrative most likely derived from the Stalinist system-Truman Institute, 1999) in a clear lack of understanding of not only the timeline of the war in the North, but also the nation itself.
In general, the massacres the Circassians were subjected to during the deportations were commonly concealed in Russian literature, and so was their resistance, because such a narrative could help realize the legitimate demands of Circassian nations, which include land rights and Genocide recognition (Lapin, 2003).
I'm giving this a star as a reader, just because the book might be useful for those who are looking for an introduction into the establishment of modern Georgia and Armenia.
