The main characters of the book are several generations of one St. Petersburg, intelligent Jewish family. The narrative begins with a description of one of the hardest days of the blockade, when the heroine Firochka turns 30 years old. However, the reader also comes across bright moments in the life of this once large and friendly family - the mother dying from hunger and illness remembers them, and the original photograph of the family presented on the first page of the cover reminds of them. Then, in 1912, all of them, including one-year-old Firochka, were happy and prosperous. The mother dies and, after the funeral, two sisters, Firochka and Katyusha, together with little Ilyusha, leave for evacuation to Omsk, to their older sister, Ritochka, and her children. Firochkin's husband Sanya remains in besieged Leningrad to continue working at a military factory and fulfill orders from the front. Thus begins this family saga, which covers approximately a hundred years of the lives of these people. The fates of their children are also described here: Ilyusha and Natasha, who already under Khrushchev and Brezhnev had to fill their troubles. And also after them, until the beginning of the 90s, until my departure to Israel.
