Reading a compendium of short stories from the so-called Golden Age of Sci-fi.
If you can believe it, I just recently ‘discovered’ Isaac Asimov, and while Science Fiction isn’t my first choice, I’ve really enjoyed his books.
They led me to Blake Crouch; his books are real mind-benders. ‘Dark Matter’ ‘Recursion’ and ‘Upgrade’ were fun.
