The story is approximately this.
A society in which it is not customary to read books, but the main character, contrary to everything, reads. It is not considered adequate, etc. As a result, it turns out that there is a closed group of people who are reading, developing different things for the majority. The protagonist is accepted into this elite of society that no one knows about.
I read for a long time. I remember that the book liked me very much. I want to read it myself and get the child.
