I loved Snow Crash (top 5 personal favourite book) and Cryptonomicon (I haven't read Seveneves yet), but I didn't like Anathem that much? (POSSIBLE SPOILERS FOLLOW) Especially the sort of quantum-ex-machina "twist" near the end was kind of off-putting to me. Everything so far was very well crafted and researched, but this part was a lot like "yeah multiple universes or something", but I'm not sure if it even works that way, if true. Also I found the constant back-translating of scientific discoveries and theorems with-a-different-name kind of tedious. I caught a lot of them, but many also not and I kept feeling like I was missing out on some cool references. Even though (IMHO) I have a pretty broad general knowledge of most important scientific/math theorems. There were some other bits I didn't like but that's personal taste. I loved the humour in Snow Crash (so much better reading than Neuromancer) and the hi-tech thriller action stuff in Cryptonomicon. Anathem seemed kind of slow, building a whole world and such (as I said, matter of taste, I don't get quite as excited about world-building in fiction/fantasy books, unlike many people).
