I’ve read Heinlein, Farmer, Clark, Niven, Pournelle, although it’s been a long long time since I’ve actually picked an actual book up and read it. I gotta get back into it.
I found a bunch of old yellow spined daw books recently at my local thrift shop, and yes I bought them all.
Might I recommend H. Beam Piper’s “Lone Star Planet”?
