This largely documentary novel about the history of two families for most of the last century is saturated not only with characters and events, but also with semantic layers, allusions, metaphors. The text is complemented by expressive black and white illustrations. On the first pages, the reader finds himself in the atmosphere of wandering – whether it's children's carefree travels, the wanderings of refugees from the First World War or the path that marks changes in life after the revolution. A girl named Olga is going to work at a rural school. She had to leave the Institute. It turned out that she had a relative who fought in the White Army. In a quiet village, the new teacher is greeted, albeit cautiously, but friendly.

But for Leonid, Olga's childhood friend, the railway from an early age was an amazing world full of secrets and adventures. His father served as an assistant station master. "The first ride on a mechanical cart was a miracle: the sound of wheels, the spring wind in your face, trees floating on the sides, and clouds rushing towards you in the high blue sky! And I want to throw my head back and scream with joy, but it takes my breath away...".

The grown-up young people meet again, and now they are heading hand in hand towards a new life in Moscow. They will have to go through a difficult path together with the whole country – repression, poor life, war... But still, there will be a magnificent garden, which they dreamed of so much, favorite books, conversations with friends, business trips, discoveries. "The prospects of atomic energy beckoned and fascinated, and Yuri Gagarin's almost two—hour flight in space was the first in the history of mankind! "everything was perceived as the first step on the path of exploration of the universe." And new generations are coming into life to make their way.
