(From the publisher):
Once second in command at NASA, Dr. Orlando Fitzmueller built a secret computer base in the Nevada desert. Through careful planning, diligent calculations, and sheer brilliance, he had developed a strategy that would help him realize his impossible dream of controlling world atomic power. It was up to the Penetrator Mark Hardin to stop Fitzmueller - and time was running out. For if the scientist's demands weren't met, he would ignite a holocaust from space that would kill 150 million people in the first thirty seconds.
