That sounds pretty painful Hope they can figure out how to help you!
Awww I think the only thing I did was nudge you a little bit at the right moment in the right direction - and everything else was your own work! (You didn’t even ask a single language or grammar question, you know?)
It is definitely really worthwhile!
The “different levels of furigana” is certainly a Japanese thing and applies to native books as well. Especially for children’s books one can usually find editions with many or all furigana, and editions with fewer furigana. The all-furigana books are often recognizable by a green border around the cover like this:
(totally unrelated, but this is a very heartwarming story about coming-of-age, with a beautiful anime)
Sometimes the all-furigana book is somewhat different from the “regular” edition (e.g. in Kino no Tabi they left out a full chapter iirc). Also of course the contents per page usually varies across different editions (which is a nightmare to keep track of in bookclubs ).
But having different phrasings indeed seems to indicate different translations. According to the book’s Wikipedia page 星の王子さま - Wikipedia there’s indeed a gazillion of them, but only very few audio recordings, as it seems.
Yes, the cover on mine looks identical.
I recently read a short story that is also available on Youtube where it is being read by a voice-actor. The story is about 40 pages and the video is about 50 minutes. He reads the story so fast that I cannot even follow with my eyes let alone read and understand anything… So, still way to go, for me as well.
I think I’m generally less affected by task switches than many other people I know. It even occasionally happens that I stop reading in the middle of a sentence (especially when reading harder books), and I can usually get back to it the next day without issues.
Also, for my sauna reading it turns out that I can read one of those 4-5 page chapters pretty much exactly in the 20 minutes that I usually take to rest between sauna rounds, so that’s a really good fit as well.
