Giants on the Earth

The Earth lies under the yoke of Jovian oppression. Glavour, the Jovian, called Son of God and Viceroy of Earth, contends with Damis the Nepthalim, half-breed son of the previous Jovian Viceroy and a human mother. Glavour is eight feet tall with the strength conferred by Jupiter's gravity. Damis is of human stature, but with his father's strength. Will it be enough? He is half-Jovian and half-human. On which side will his loyalties fall? Can he assist the people of Earth in a revolt against their masters?
