I just finished the Commonwealth Saga + The Void Trilogy by Peter F. Hamilton, loved it. Both set in the same universe, the first two in the relatively near future (about 300 years from now), the trilogy in the far future (about 1500 years from now).
The trilogy can get a bit abstract, verging on the fantasy genre at times, but in the end the author manages to give an explanation that "makes sense" for everything, which is the thing I really like about his stories. Highly entertaining.
It's a bit of a dubious explanation of The Void, to be honest (although the "Think of it as an 8-dimensional onion" kind of makes up for it), and the ending is a little weak, but overall I enjoyed the series a lot. The alternating of space opera/fantasy chapters is also done pretty well, and keeps things interesting.
