If you've not read any of Greg Egan's books this is your lucky day - an incredible writer to discover! His books have an unusually high ideas/page ratio, and are very readable.
For some definition of readable. Be prepared to have yours eyes glaze over at certain points, but it's well worth the struggle to push on through.
I've had friends mention that they liked Neal Stephenson's "Cryptonomicon", except for the lengthy digressions into mathematics. One day, I'll get mad at them, and get revenge by suggesting an Egan novel.
That's funny: the only thing I usually like about Neal Stephenson books are the digressions into nonfictional material. Everything else is just a needless exercise in people being shitty to one-another and Stephenson re-announcing his belief in '90s-era "hacker" ideologies.
