Ask HN: Which book would you pick to re-read for the rest of your life?

Röde Orm / The Long Ships by Frans G. Bengtsson: https://en.wikipedia.org/wiki/The_Long_Ships

I guess it's a swedish favourite, a viking historical fiction / adventure novel. Fond memories since I was a teenager. I have only read it twice.

Great choice.

Ah! I have this on my table right now.

it's a quadrilogy, not a book, but I'd pick Ada Palmer's _Terra Ignota_ series without hesitation. I'm comfortable arguing for it fitting within the constraint of the question, largely because it is making one sustained argument that's carried out throughout the entire series -- it's very much one book that happens to be like 4000 pages long rather than four separate books.

Anyway, Ada Palmer is a sci-fi writer whose day job is as a professor of Renaissance and Enlightenment-era European philosophy, and everything in this series (set in the 2500s in a world where the geographical nation state collapsed and world governments are now large voluntary organizations) is heavily informed by her training as a historian of philosophy.

She finished the series last year, and though each book has gotten nominated for the big awards, she's had the misfortune of publishing on more or less the same schedule as N.K. Jemisin, whose stuff typically wins the Hugo, Nebula, or both. The fandom is teensy tiny -- I've seen it described as "six people and a shoelace" -- but most people who read it get fanatically devoted to it.

The Book of the New Sun. I've already read it 6-ish times, with a different interpretation every time, and I have every reason to believe that would continue indefinitely. I would say The Book of the Long Sun and The Book of the Short Sun, since I like them better, but there's no way to justify calling them one book when, even in fiction, they're 2 different books.
