About the book: year / "Kolovrat" - Afghanistan. The end of the war with the Mujahideen. Special forces are establishing order in the Kunar province adjacent to Pakistan. While chasing the Stingers, Kondraty Lvovich Zarubin, a hereditary Cossack and a special forces captain of the 334th Separate Special Forces Detachment of the GRU, falls into a trap with his men. After an explosion in a dugout filled with explosives, his spirit is transported back in time. When he wakes up, he discovers that he is now living in someone else's body. Here he is called Evpatiy Kolovrat. He is a boyar and military leader who serves the Ryazan prince Yuri. The year is 1235 A.D. There are still a couple of years left before Batu’s invasion, during which Rus' will tremble, and Ryazan will be the first to be burned. While a shaky peace reigns all around. The princes indulge in civil strife. No one has heard of the Tatars since the Battle of Kalka. And only one person knows that there is no time to waste. And what needs to be done to change fate. “The Battle of Kalka” is an alternative history with a strong bias towards humor. Moreover, he began writing it under the pseudonym A.Ya. Zhivoy precisely as a humorous work based on real historical events. The transition point is the first meeting of the Russians with the Mongol army in the history of ancient Rus', which ended with a close acquaintance of these peoples on the banks of the Kalka River in 1223 AD. This meeting could not but have a huge impact on the history of the two peoples. Only the result was completely unexpected. Contents: 1. Alexey I'm Alive: Kolovrat. Sign 2.
