When a book is ground in what many like to call reality, that is, a work that is set in the here and now, or near future it by this distinction cannot be scifi. At least not marketed as such. Instead you will see it appear under the techno thrillers heading, because sci-fi still ostensibly carries a deep rooted stigma preventing any sort of mass market appeal.
Some of the works that come to mind are Michael Crichton's "The Andromeda Strain" and "The Terminal Man," while both a bit dated, still lend themselves to enjoyable reads. At the time of publication they were not considered sci-fi. Though even with many of the points being proven, either right or wrong, they are still quite clearly sci-fi of the era. When I read them they were still contemporary, yet today they still work well as seventies period pieces now and you can almost get a feeling that you have been taken back in time. Even today I can still pick up "The Andromeda Strain" and read it cover to cover before I know what's happened.
Other books I have found myself enjoying:
- "Zoo" by James Patterson
- "The Business" by Iain Banks
- "Deep Storm" by Lincoln Child
- "Rainbows End" by Vernor Vinge
- "Kong Reborn" by Russell Blackford
- "Deception Point" by Dan Brown
As well as the under rated "The First Fifteen Lives Of Harry August.
