About the book: 2019 / Borgus Nicholsen remains a mystery in the history of Soviet science fiction. In 1924 and 1927, this unknown writer with a “Scandinavian” pseudonym published the adventure-fantasy duology “Gloriana” and “Massena” about the incredible adventures of the American Jack Schwind, who stole an invisibility device - and then literally disappeared into thin air, like his hero. Now, in the Polaris series, both novels by Borgus Nicholsen return to readers.
