The main character’s life boils at night, all because of Gunther’s illness or “fear of the sun.” He spends his days locked up, has no friends, and his parents have died. A random night walk dramatically changes the hero's fate. It's all because of a notebook that fell straight from the sky. The notebook turned out to be the diary of a girl from the future, who sent him to the past with the hope of changing the unenviable fate of humanity. The story begins in the fall of 2022, just a year before the Apocalypse, when millions of people disappeared around the world, and creatures called arbiters descended to Earth. Will a very young boy be able to change the fate of humanity, will he become its savior, or will all efforts be in vain? We will find out all this later, but for now the main character faces many hardships and dangers in the new world called Vilestria.
