Hawksbill Station (1978) by Robert Silverberg

A "dark, restrained, and powerful" mirror of current politics from the Science Fiction Grand Master ( Science Fiction Ruminations ).

In the barren landscape of the late Cambrian period, a penal colony sits high above the ocean on the east coast of what would become the United States. The men-political prisoners-have been sent from the twenty-first century on a one-way ticket to a lifetime of exile. Their lonely existence has taken its toll . . .

Jim Barrett was once the physically imposing leader of an underground movement dedicated to toppling America's totalitarian government. Now he is nothing but a crippled old man, the camp's de facto ruler due to his seniority. His mind is still sharp, having yet to succumb to the psychosis that claims more and more men each day. So when a new prisoner is transported to the colony-a startlingly young and suspiciously apolitical man-Barrett's instincts go on high alert.

As Barrett reminisces about his revolutionary past, he uncovers the new prisoner's secrets-and faces a shocking revelation that thrusts him into a future he never dreamed possible . . .
