I'm not sure if it's true, but QI claimed that most people who claim to have read 1984 are lying.

Why would you pretend to have read a ~300 page book, just read the bloody thing.

It's a bit boring and depressing, I stopped reading midway through. But it illustrates an important point.

I see your Seveneves! For me it's Anathem. Though the fact that it's the only Stephenson book I have a hard copy of probably helps with serendipitous rereads of the kind you describe.

I read Seveneves once from the library and wouldn't mind reading it again though.

I've read The Sprawl books (trilogy?), but accidentally did it out of order and separated by years, so it took me an embarrassingly long time to make some connections. I should read them again in order this time!

Have you tried "The player of games"? Based on the others you have there you might like it.

I've read eight of the Culture novels now, and "The Player of Games" was in the bottom two for me. I'm mystified that most others seem to rank this book so high. "Use of Weapons" and "Surface Detail" are my favorites so far, but they're rarely mentioned here.

I adore the Culture novels, but I read them for the first time last year.

So far I have only re-read Inversions and Excession, the two that were the most fun the first time through.
