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!
