One Anya lives in Saint Petersburg, and she has a sister in Moscow. The other Anya lives in Moscow, and she also has a sister—the very same one from Petersburg. The third cousins Anya resemble each other like... Red Square and Nevsky Prospect! Muscovites and Petersburgers are very different. The heroines of Tatyana Mart’s stories discover this while visiting both capitals alternately. Less than seven hundred kilometers between the cities—and people even speak a little differently. In Moscow, a white bun is somehow called bread (although everyone knows bread is black), but in Petersburg, they say pishki instead of donuts, and porches are called parade entrances. And actually, Peter could very well have been called Moscow. Any reader aged 8-12 will easily recognize themselves in the stories’ heroines. The girls find themselves in a series of amusing situations caused by differences in worldview. But behind the linguistic and cultural differences, behind the comparison of the cities, behind the joys and quarrels of the heroines lies an important subtext: to learn to understand another person, you need to be able to see the world through their eyes. Essentially, this is what the book tells readers of primary and middle school age, beautifully and somewhat ironically illustrated by artist Sergey Gavrilov. The young writer Tatyana Mart is a Petersburg native, a philologist by education, a literary editor and reviewer for the website "Papmambook," dedicated to contemporary children's literature. Her works have been included in long and short lists of well-known prizes. The new stories—alive and vivid—will be interesting for children, adults, and not only for residents of the two capitals. For primary and middle school age.
