The Lost Continent by Edgar Rice Burroughs, Science Fiction

Set in 2137, the narrative explores a post-apocalyptic world shaped by a cataclysmic war that ended the Old World. America has survived through extreme isolationism, with no contact beyond the thirtieth parallel for two centuries. When Lieutenant Jefferson Turck's ship is damaged during a storm, he defies the isolationist laws and lands in a desolate England. There, he discovers a Europe that has transformed into a ruined landscape, devoid of the enmity or camaraderie that once defined it, prompting questions about survival and connection in a changed world.
