I've read a number of outstanding science-fiction stories, including a few that aren't focused on technological changes, but societal changes in the future.
Thirteen by Richard K. Morgan
Altered Carbon by Richard K. Morgan
The rest of the books by him are excellent as well.
All of them are set in a dystopian, cyberpunk future, but unlike more cyberpunk, is more distant in the future.
From Wikipedia:

The premise behind his book is extremely interesting and makes for a great read.
Also, check out the Xenogenesis series of books by Octavia E. Butler. They are books involving extraterrestrials, which I'm not normally interested. But Butlers version of aliens and what they might be like is the most unique thing I've ever read. Her other books are also definitely worth reading.
The works of Isaac Asimov are also extremely interesting for those who enjoy hard sci-fi, and his premises are always extremely believable and realistic. Of course there is the classic work I, Robot, as well as a book called Nine Tomorrows which I STRONGLY recommend.
The work The Sleeper Awakes by H. G. Wells is also very good, and his view of the world of the future is not dissimilar from much later scifi. The thing I didn't like about the book was that it is written in a rather archaic late Victorian style. That's the unique thing about Wells' writing. I didn't like the style, just the ideas he presented, so if that sort of archaic writing style doesn't bother you, then you'll enjoy the story.
