Mac Reynolds (Dallas McCord Reynolds) did not receive any awards, nor was he awarded the title of Grand Master of Science Fiction. But almost every one of his works caused truly violent scandals. But it was he who came up with a unique OPP - the Organization of the United Planets. Planets with the most impossible and incredible political, social and cultural systems, existing in a very fragile balance. When this balance is disrupted (or threatens to be disrupted), the work of secret agents of the UPP begins!.. Before you are fascinating detectives of the distant future. Are you in doubt? Read - and check it out for yourself!..
