All three books are very highly rated by hundreds of reviewers in the US store. Looks like a good read.

Kamas, Utah, 2024. America has become a totalitarian dystopia after the Unionist Party's rise to power. The American West contains vast Restricted Zones dotted with ghost towns, scattered military garrisons and corrective labor camps where the regime disposes of its real and suspected enemies.

A former businessman from Pittsburgh, Paul Wagner, arrives at a labor camp in Utah's Kamas Valley. He is unaware that his eleven-year-old daughter, Claire, has set off to Utah to find him. By an odd quirk of fate, Claire has traveled on the same train that carried her father into internal exile.

The second book in the Kamas Trilogy begins five years after the Kamas revolt. A Kamas survivor who returns to Boston is ordered by the prisoners’ covert Star Committee to kill the commandant who crushed the revolt.

EXILE HUNTER, the third book in the Kamas Trilogy, begins in 2023, one year before the Kamas revolt, in a dystopian America ruled by a tyrannical President-for-Life who turns America’s military and intelligence assets against his domestic enemies. The protagonist, an undercover officer specializing in targeting exiled political opponents, becomes the scapegoat for a failed operation and is sent to die in a corrective labor camp near the Arctic Circle. But, defying all odds, he survives, escapes and devotes his remaining energies to finding and aiding a woman whose family he has ruined.
