The Baroque Cycle was a lot of heavy chewing, but it was ultimately a pretty good story, and I was sad to come to the end of it. It's also, along with Cryptonomicon, one of the more interesting explorations of the world of money and finance I've found.
You might also enjoy REAMDE which it a bit faster-paced. I happened to enjoy Anathem as well, though that was also a bit of a slog. It did have a resolution though. And protractor.
Read all but Anathem. I'm still convinced Cryptonomicon is the pinnacle of his writing, and it's downhill from there. The story in Baroque Cycle was great, but good god, that thing needed an editor to do some serious cutting.
REAMDE was quick and entertaining, but it was the equivalent of a Tom Clancy novel. Or, fine, Michael Crichton.
