A book about the life of the river and its inhabitants throughout the year. There are many great rivers: Nile, Amazon, Mississippi, Ganges, Yellow River, and each forms an integral part of the nature, history, and culture of the country or countries through which it flows.

In Russia, the most important and the largest river is the Volga. It crosses several climatic zones. A variety of birds, fish, and animals live nearby and around it. 

Which animals consider it home, and which just come to visit? People changed the Volga dramatically while adapting it to their needs.
