07 - Inside Earth by Poul William Anderson

In a not-so-distant future, Earth has fallen under the iron grip of the Valgolians, a humanoid race that extracts heavy taxes, controls industries, and meddles in every facet of life. As rumors of their brutal regime and horrific massacres spread, a flicker of rebellion ignites among the patriots yearning for freedom. Yet, not everyone shares this desire for liberation; the end of nationalistic wars has brought an unexpected peace, and access to healthcare is now widespread. Amidst this complex landscape, a faction of elite intellectuals conspires to overthrow their oppressors, but their efforts are hindered by deep-seated prejudices and divisions among the Earths populace. The conquerors are keenly aware of this discord, using it to their advantage. Can a united front emerge from the ashes of hatred and mistrust, or will the dream of freedom be extinguished once more?
