The Forever War Kindle Edition for 25 cents
by Mark Frauenfelder from on (#248XS)
"To say that The Forever War is the best science fiction war novel ever written is to damn it with faint praise. It is, for all its techno-extrapolative brilliance, as fine and woundingly genuine a war story as any I've read." - William Gibson
I bought it, and added the audiobook version for $3.50.
