Boy from the Future. Youth. Novik

Could a not-so-simple boy from an ordinary Moscow orphanage even dream of being transported from the Russian Federation of 2016 to the Soviet Union of 1969?
No, he could indeed dream. The reason: slipped, fell, woke up. The consequence: concussion, cast,... oh no… surprise, joy, and the past all around. Restless in the turbulent sea of worlds. Another hit and again a new world. 1903, very little time left before the Russo-Japanese War, and Max simply cannot miss such fun. So, again, everything is in a rush, again, everything is in haste. The main thing is to keep up.
Still, Max managed to keep up. The Russo-Japanese War began just as it did in reality, advice and information did not help. However, the story took a slightly different turn thanks to Max. But a third party decided to intervene in the war and is doing so, as always, boldly and cynically.
