Rebel billionaire Dan Randolph--possessor of the largest privately owned company in space--intends to weaken the stranglehold the new despotic masters of the solar system have on the lucrative ore industry. But when the mineral-rich asteroid he sets in orbit around the earth is commandeered by the enemy, and his unarmed workers are slaughtered in cold blood, the course of Randolph's life is changed forever. Now cataclysm is aimed at the exposed heart of America--a potential catastrophe that Randolph himself inadvertently set in motion.
