In this book, the history of the city of Novosibirsk appears in an unusual form - through the prism of the history of another city, Novonikolaevsk. Their images are each unique in their own way and at the same time so closely intertwined that they are already inseparable from each other. Of course, neither one nor the other is ignored, because in fact it is one city, but at the same time - two completely different ones.
