The cultural references in science fiction can be difficult to translate. A story might reference a particular historical event or a cultural icon from the author's home country. Translators need to either find a similar reference in the target culture or find a way to explain it without losing the essence of the story. For example, if a science - fiction story in the US mentions the Apollo moon landings as a reference for a future space exploration mission, a translator into a language of a country with no such space - faring history needs to be creative.
Well, a 'vanished novel' can be understood as a novel that has ceased to be accessible. There are numerous reasons for this. It could be that the author chose to withdraw it from circulation for personal reasons. Another possibility is that the publisher went out of business and the copies of the novel were not re - printed or distributed further, causing it to gradually vanish from the literary scene.
One of the best ways is to have a deep understanding of both the source and target languages' cultural backgrounds. Science fiction often contains unique concepts, so being familiar with the genre's common tropes in different cultures helps. For example, in English - speaking countries, some science - fiction concepts like time travel are very common, but they might be expressed differently in other languages. Translators also need to be good at handling technical terms which are abundant in science fiction.
I'm not entirely sure specifically about 'Harry Crow traduction fanfiction' as it's not a widely known mainstream title. It could be a fan - created work related to a character named Harry Crow, perhaps in a particular fictional universe where someone has written their own stories (fanfiction) and translated them ('traduction').
Since I don't have detailed knowledge of 'Vanished a Novel', it could be a thriller where a key item or a crucial witness vanishes, and the main character, who could be a detective or an ordinary person caught up in extraordinary circumstances, has to race against time to find out what happened before it's too late. There might be twists and turns involving different characters' motives and secrets that are gradually revealed as the story progresses.
