Salt of the Earth by Alan D. Hansen

Young, visionary scientist, Marshall Salt believes humanity’s future lies in the asteroid belt. With his closest friends, he has developed groundbreaking technology capable of extracting untold wealth from the cosmos.

Their ambitions come with a staggering price tag - tens of billions of dollars. To fund their dream, Marshall must turn to the last person he ever wanted to ask: his estranged father and reclusive billionaire, Arthur Salt.

As they uncover the ambitions of global power players like the Manifest Destiny Cartel, the Cibola project becomes a battlefield for control over humanity’s future in space. Meanwhile, Arthur Salt wages his own war back on Earth, navigating political manipulation, financial ruin, and legal battles - all while seeking redemption and connection with his son.

Alan D. Hansen's SALT OF THE EARTH is a gripping sci-fi epic that blends cutting-edge technology and adventure with a deeply human story of family and reconciliation.
