The Amber Series by Roger Zelazny
We All Died At Breakaway Station by Richard C. Meredith
I firmly believe that "We All Died At Breakaway Station" is the best combat science-fiction novel ever written.
I liked Foundation and just about all the other pre-1970 Sci-fi books that will be mentioned in this thread, but the Sci-fi book that changed my life was the 1909 book “The Machine Stops” by E. M. Forster, which I read as a boy.

Impossible to say.
one that sticks out in my mind is The Boat of a Million Years.—1989 by Poul Anderson. Past sci fi golden age and I could probably think of a few better ones if I studied it for a while.
still, it was good.
