The Rock Rats

by Ben Bova

Published 7 February 2002
Martin Humphries - the fabulously wealthy, coldly ruthless owner of the greatest space-based industrial giant - has been checked, but his malice and ambition remain. He still dreams of bankrupting the rival space exploration company Astro Manufacturing and bringing the independent prospectors who are beginning to stake claims on large and small rocks of the Asteroid Belt under his control. And most of all, he wants to capture the love of beautiful Amanda Cunningham, the woman who spurned his money, and take his revenge on Lars Fuchs, the space prospector who both defied Humphries and married Amanda. His weapons will be piracy, sabotage and murder. The Asteroid Wars have entered a violent new era.
