Once every twenty-five thousand years

In the hot summer of 2018, writer and translator Alena travels to Sweden once again. This time to swim in Stockholm's lakes and work with her family archive. She plans to live in her older friend Margareta's empty apartment in the Vasastan district, whose rooftops are actually run by repairmen, not Karlsson.
Secretly from everyone, Elena is waiting to meet Tunci, a former Sudanese classmate from Swedish class, who broke off their friendship for a long time without any explanation. Now Elena will get it. However, against the backdrop of apocalyptic weather, her plans are also ruined, everything is not going as planned.
Alena and Tuntsi almost witness a rare astronomical phenomenon, but for them it never happens. So was there a sign in the sky or not? And is it worth counting on any celestial signs as advisors in your life? Alena continues to think about all this, having returned to Belarus.
The story can be read as a sequel to Anka Upala's previous novel, "On a Snowy Island," or as a stand-alone book.
