Hawksbill Station (1967)
by Robert Silverberg Political prisoners are sentenced to exile in a Paleozoic gulag hundreds of millions of years in the past, before the appearance of the first land-dwelling lifeforms. The story alternates between the exiles in the past, aging and battling mental illness brought on by their isolation, and the activities that resulted in their sentences. The primary character, Jim Barrett, struggles to maintain his deteriorating community while investigating the puzzle of a new prisoner who is unlike any of the others. The end is a bit unsatisfying--merely a conversation that wraps up the various plot points.
