Ok, what book do you remember?
Which Sci/Fi book do you remember best?
Honestly, I can't pick one. But there are several that still stick with me.
The Stars My Destination, A Bester.
Anything from Niven's early career.
The Sheep Look Up, Stand on Zanzibar, Brunner.
Hienlien, Bradbury, Asimov, Spider Robinson*, lord and so many more.
(*If I ever find a place like Callahan's, moving in permanently.)
