I just finished reading Peter F Hamilton's Void Trilogy. It's taken a long time!
Despite the story being extraordinarily long (and perhaps drawn out, though not nearly as bad as Lord of The Rings) it's pretty epic. It's set so far in to the future that some of the technology is hard to get your head around. It introduces quite a few ideas, such as what if we could share emotions directly? As with many of his books, he kind of puts ideas in there, but doesn't dwell on discussing pros/cons. However, this story does do some exploration of how good ideas can go pretty 'wrong'.
There's a fair bit of morality, and techno-spirituality even.
