Tom Clancy's Chain of command - Marc Cameron

PRE-ORDER THE GRIPPING NEW THRILLER IN TOM CLANCY'S JACK RYAN SERIES - INSPIRATION FOR THE BLOCKBUSTER AMAZON PRIME TV SERIES

America is under attack from within. Patients in hospitals, clinics, and at home are dying when the drugs they need for survival turn out to be ineffective copies. A corrupt pharmaceutical billionaire has spent millions supporting radical groups while using the chaos they engender to cover his money-making schemes, but for a man with such towering ambitions, the only real goal is power.

To get that, he'll have to eliminate the only impediment in his path -- Jack Ryan. The question is, how do you attack the most closely guarded man in the world?

For a man who has built his fortune on underhanded dealings and misdirection, the answer is as simple as it is shocking:

He'll have to kidnap the First Lady.
