51 of the Best Science Fiction Books and Novels of All Time

[Goodchild]

I also agree with Spacetime that Macroscope by Piers Anthony would be a good inclusion, it's an amazing sci-fi book.

I have not read Macroscope. I am relatively sure that the only books by Piers Anthony that I have read are the Magic of Xanth series, and the Blue Adept series, and I am not sure either one would qualify for my top 50 list.

I very much recommend Macroscope, it's pure sci-fi from Anthony but written in his style. It gets a little metaphysical towards the end but mostly in the sense that you're really not sure what the titular Macroscope is capable of doing. It's probably my favorite book by Anthony, including On a Pale Horse which you listed for yourself.
