If you suddenly thought that the series of books “Several Cases of Captain Astanov” are different stories that are in no way connected with each other, then you are deeply mistaken. Each individual adventure is an important element in one big investigation of the captain, who, by the will of fate, became one of its main participants. The entire series consists of five books and I am pleased to present to you the fourth part, called “Botany”. We will talk about two small ones planets that suddenly appeared in the spotlight of the Earth's military control. Of course, I won’t tell you what exactly connects them and how they became part of a larger investigation. But I will say one thing, after this case, the whole story will move to a completely different level, and events will begin to develop much more rapidly than before.
