That's interesting! I have a similar experience but for the opposite reason. I like the book and have enjoyed reading it several times, and listened to the audiobook just before the pandemic.
I know I like it and consider it to be a good book, but every time it's like I'm reading it for the first time. I can only remember thew "mood" so to speak, nothing about when, where, who, what. Even now, just 5 years after the last time.
I think it is related to Gibson's prose, but I remember Pattern Recognition quite well despite having read that only once.
Neuromancer is just a complete blank, except I know I like it. Wonder if anyone else has had a similar experience with a book?
That book was the main impetus for me connecting to the Internet, installing Linux and getting involved with the European hacking underground of the mid to late 90s. I also periodically re-read it (now in English): the prose still seems razor-sharp and the divergent feelings are still being evoked. Plus, it's an insanely hyperstitional book: one gets the feeling that Gibson (whose non-Sprawl work pales in comparison and who has never again reached these heights) didn't just write a heist-story filled with countercultural sensibilities but channeled something greater, something that has been intricately involved with how the world we experience has evolved.
Looking back on those days, I now wish I'd read it in English for the first time. The Greek translation is not bad but it feels kind of archaic and doesn't do justice to the brilliance of Gibson's dystopian vision.
PS I read the one by AQUARIUS
