Snow Crash and Cryptonomicon are among my favorites. I’m also a bit of a sucker for the techno-futuristic theme of the former, and echno-enthusiasm theme of the latter. Growing up as an IT geek in the 90’s made a lot of it strike a home run with me.

Rise and Fall of the D.O.D.O. is pretty cool. It’s written as an epistolary of letters, diary entries, corporate memos, and voicemails, which gives it an interesting and fun angle.
