While respectable luminaries of earthly science are searching in depth for the key to the riddle of the death of an alien civilization, the main character, a young girl, is just trying to understand her own feelings. Only for some reason it is this young trainee who is the first to find the answers to all the questions, and not the world-famous “luminaries.” The third book of the fantastic trilogy “Labyrinth for Troglodytes” is about the problems of contact with extraterrestrial civilizations. In this series, Olga Larionova managed to find a rare and successful combination of borderland romance, distant travels and unknown islands with a purely female view of the world, when the paramount importance for the author and hero is not the series of events itself, but how what is happening will affect the relationships between people.
