Armageddon 2419 A.D. by Philip Francis Nowlan
From 1919 comes the original “Buck” Rogers novel. He wasn’t called “Buck” until later, after the comic strip picked up steam. Here he is just Anthony “Tony” Rogers, a WWI vet trapped in a cave mine and emerges centuries later to help lead the second American revolution as they take down the Han Overlords who took over the world centuries eariler. A good solid adventure story with a couple of decent and one really bad sequels written decades later.
