I just finished reading Cryptonomicon and Anathem, both by Neal Stephenson. If you're into extensively-researched thrillers, I'd give them a try. Both are over 1000 pages long.
You can try out Blindsight by Peter Watts from here, and if you really like it (like I did) you can go buy Echopraxia. The rifters books, in comparison, are kind of shallow.
Besides that, I don't have any outstanding recommendations in recent memory.
