Just finished Anathem the other day. I've read two of Stephenson's books now (the other being Cryptonomicon), and I thought both were brilliant. I never have a shortage of non-fiction to read, but I'm now in the hunt for my next novel. The couple that I've searched my local library for are checked out at the moment, so any rec's would be appreciated.
Eye of the Needle by Ken Follett. When I asked my mentor to make a recommendation of a well-paced thriller, that's what he gave me. It's technically excellent and enveloping. Truly a gripping read. And if you find Stephenson to be brilliant you'll probably be done with Follett in a bathroom break. I gave up on Cryptonomicon about 12 hours into it 'cuz I just couldn't give a shit.
Cryptonomicon is a lot of fun if you know/are the sort of people he's writing about, but I'm constantly surprised it gets recommended outside of techy circles. It's like a big collection of in-jokes and history of cryptography and computing with a half-assed thriller plot to sort of tie it together.
