The new novel by the author of the series about Lothar the Yellowhead is written in the genre of “hard” science fiction. Imagine an ordinary Central Russian town, a Soviet regional center from 1967, inexplicably transported by unknown experimenters to God knows where... not even to another planet, but to the inner surface of a huge artificial formation - a Dyson sphere - where millions of worlds can coexist... Difficult tests from the very first days are issued to the residents of the city. The hardships of the war for existence against a hostile and completely alien environment are aggravated by the sluggish and clueless leadership of the regional center; so the whole burden of the struggle and the search for the right solutions falls on the shoulders of individuals, yesterday’s boys. Finding your place in this strange world, and at the same time dealing with internal problems, is the only way to survival... The book includes the first two works from the “World of Eternal Noon” series: The Problem of Survival (novel), pp. 5-194 Starting Place (novel) , pp. 195-409
