About the book: 2021 / 1641. Four years have passed since the Cossacks captured the Turkish fortress of Azov, blocking the exit from the Don to the sea. Meanwhile, the Turkish Sultan gathered troops and, sending them to Azov, gave the order to recapture the fortress at any cost. But the Cossacks in Azov are going to stand to the end - even against the entire Turetsk region! Even if enemy cannons turn the fortress into ruins. Even if thousands of good guys die in this battle. For too long, the Turks and their allied Tatars ravaged the southern Russian land. Too many people are slaughtered or taken into captivity, and slaves have a worse life than livestock. It's time to get even! And this act of the Cossacks will go down in history as the famous “Azov seat.”».
