You wrote "sci" , not "sci fi"
So there I was thinking somebody might like to be directed to " The Elegant Universe " Brian Greene, or "The Periodic Table" Primo Levi, or "E = M C^2" David Bodanis or "Surely you're joking , Mr. Feynman" Richard Feynman or " Bridges to Infinity" Michael Guillen or ...........
But no - you want the pale cousin.....
early Kurt Vonnegut " Cats Cradle", "Sirens of Titan", "Slaughterhouse 5", "Player piano"
John Varley " Titan"
Larry Niven " Mote in God's Eye", "Ringworld"
Ian Banks "Excession"
Trying to think if Joe Haldeman ever scaled the heights of the "Forever War" again - don't think he did
How old are you? Up to a really great book ? Demands you know heaps of the history of science and philosophy.."Eifelheim" Michael Flynn... best book I've read in the last 200.
Enough enough.... bedtime.
