The novel describes the events of our time, the main character of which is the young scientist Naukov. The novel is not science fiction in the strictest sense, although the discovery made by the scientist did not actually happen. Actions in the novel unfold as if this discovery took place in real life. Its essence was that the substance invented by the scientist had an effect on millions of women and men, forcing them to fall in love with each other on May Day night and indulge in love, as a result of which all women who fell under the influence of this love, regardless of age and ability to bear children, became pregnant and were supposed to give birth to twin boys. The ambiguous attitude of society towards the possibility of an unexpected population explosion also caused various diametrically opposed actions towards the scientist. Some idolized him, while others found him in their throats. Therefore, in the novel there are government officials with security forces, journalists, a foreign agent and representatives of the armed forces. The action-packed novel examines complex sociological problems of society in artistic form. It contains both love and hate, lyrical paintings and political conflicts. For the reader, everything that happens in the book is always unpredictable, just as the ending of the work is not predictable until the last pages. The novel is designed for a wide reader.
