Gold in the Sky (Unabridged‪)‬

Brothers Greg and Tom Hunter are shocked at the news that their father Roger had died in an accident while prospecting for ore in the Asteroid Belt, but a too-generous buy-out offer from the powerful but unethical Jupiter Equilateral Corporation suggests it may not have been an accident at all. Roger had hit something big - really big - and Greg and Tom want to find out what. But will they live long enough to solve the mystery out in the lawless Belt with an evil corporation poised to jump their claim?

An action-packed space adventure classic by Alan E. Nourse.
