There is a war going on in Ukraine. A large city is under constant shelling, Russian missiles are destroying residential houses. Mobilized men are sent to the front. Civilians are hiding in subways and basements, sitting without light, trying to survive. And black snow flurries sweep through the snowy streets, which no one can see. Angry, hungry black snow. No one? Some people do see it. The living must be saved. But, as it turns out, not only the living must be saved. The black snowstorm and the "tenants", who by the will of fate were next to the living, will bring together police sergeant Roman Golosiy and the boy Valerka, two unusual people - and from this moment begins their common history, or rather, the twelve stories of this book. The novel "Black Snowstorm" was written by Dmitry Gromov and Oleg Ladyzhensky in 2023, from January to November - step by step, chapter by chapter, to the accompaniment of air raid sirens.
