I just started Dungeon Crawler Carl. In it he fights a Spanish speaking boss. The Spanish is not translated (so far) and if you can read it, it really changes the mood and impact of the entire scene.
Are there any other books that hide significant plot points behind the use of foreign language?
I don’t remember exactly now, but yeah I think I had an edition that didn’t have any footnotes or translations or commentary, just the original text in Russian and French.
Sounds like an absolute torture with that book
