Giant spiders and tiny people, bloody battles of ants, desperate battles of microbes, travel inside the human body and unimaginable universes contained in atoms - penetration into the microworld has long been the cherished dream of science fiction writers. The anthology “Battle of Monsters” begins publication in the “Polaris” series forgotten and rare works, united by the common theme of “adventures in the microworld.” The anthology includes works from the 1890s to the 1920s.
