Ivan Efremov is a writer who radically changed the face of domestic fiction with a utopian novel about the distant future of the Earth “The Andromeda Nebula”. Under the same cover with him is its continuation - "Hour of the Bull", where the action takes place after 300 years on the planet Tormans, located on the "edge of the Universe". The collection also includes the story "Heart of the Snake" and the story "Five paintings", created by the author within the same world - the world of the Great Ring, as well as another famous novel by Ivan Efremov - "The Blade of the Razor", which can equally be attributed to both the fantastic and the esoteric genre.
