About the book: 2018 / The third and final book of the "Seterra" series by Diana Ibragimova, winner of the VIII season of the literary competition "New Children's Book". Above the world of Seterra will soon rise again black sun. But not as usual, on the third day, but suddenly, burning all the people without exception. Kayoshi, Astre, Niko, Lipkud and their friends - both corrupted and ordinary people - continue to implement the plan of Takalam and Ri. But the further it goes, the more it seems that it is impossible to do this: the cripple loses his second arm, the artist languishes in prison, the seer no longer has prophetic dreams, and the young authorities are overtaken by murderers... However, if they fail, no one will survive the eclipse.
