I’m currently re-reading Seveneves, and will probably tuck into Cryptonomicon (for the third time) in the next few months. Neal Stephenson’s books are rich enough that I usually get a different vibe from them when I read them again. For instance, on first read I liked the second part of Seveneves better than the first part, and now it’s the other way around. Maybe it’s due to the fact that on first read I get sucked in by the plot twists and on later reads I can enjoy the scenery and pick up different themes.
