Vladimir Korn is a modern Russian writer, author of popular adventure science-fiction novels. We present in audio format the fourth book of his “The Theoretician” cycle. Igor Chernigovsky doesn’t know what “offense” led him to another world, but he quickly realizes that here you can die in an instant—either at the hands of bandits or from the teeth of a predatory monster. Sticking with one of the gangs, the hero gets the nickname The Theoretician and learns the main rules: don’t talk too much and don’t trust anyone. Igor’s character was tempered through harsh travel and fights with enemies. He becomes the leader of his squad and intends, no matter what, to reach the Star City—despite the fact that the person he loves has been kidnapped and is very dear to him.
