It still happened: Sakha fell into the pool - for the first time in her life, she plunged headlong into the water! She's probably the only one in town who can't swim. 15-year-old Sakha spent a quarter of an hour underwater, but did not drown. Perhaps she should thank the hated Carilla Touchi, who pushed her into the pool? After all, otherwise the heroine would not have met Pigrit and would not have learned that she could breathe under water. The heroes of the book by Andreas Eschbach live in Australia in 2151. But in the coastal town of Seahaven, many 22nd-century advances are strictly prohibited. First of all, gadgets that change the appearance of a person and genetic manipulations. Here people still remember the sad fate of a child prodigy with six fingers on each hand, who could not withstand the pressure of his own parents. It is here, in Sihevan, that the human right to his own, “natural” life is sacredly revered. The revealed secret turns the girl into an outcast and she faces deportation. And few realize that Sakha can become a mediator between worlds.Andreas Eschbach (born 1959) is a popular German science fiction writer known for his focus on environmental issues; four-time winner of the German Kurd Lasswitz Science Fiction Prize. His novels have been filmed several times in Germany and translated into dozens of languages. And the “Antipodes” series, which opens with the book “Aquamarine,” has become one of the most discussed in the author’s homeland. The point is not only in the socio-political message embedded in the text, but also in the detailed world of the distant future: its structure in itself is a reason for thought and discussion.
