Gold in the Sky launches a hard-driving interplanetary adventure where family loyalty, corporate greed, and the promise of asteroid wealth collide. Greg Hunter, a fearless test pilot, and his brother Tom are drawn from Mars into a deadly struggle over their father Roger's mining claims in the Asteroid Belt, where a single discovery can mean fortune—or murder. When Roger dies under suspicious circumstances, the brothers refuse to accept the official story, especially as the powerful Jupiter Equilateral company moves quickly to buy out the family's ships and rights. From the harsh Martian desert to hostile orbit-ships and the vacuum between worlds, the Hunters face betrayal, imprisonment, and desperate gambles for survival. Tom's daring plan to escape and Greg's captivity under Merrill Tawney deepen the tension as the search for the truth exposes a frontier ruled by risk, ambition, and ruthless power. Fast-paced and classic in spirit, this is science fiction of perilous flight, mining frontier grit, and a family fight that could reshape the future of space.
