Used book – Power games 2: Ruthless.com, Tom Clancy

Today, encryption software protects the codes used by communication networks and security systems. Authorizing the free export of these advanced technologies would represent huge gains but would give spies and terrorists access to secret data essential for security. When Roger Gordian, CEO of UpLink, a world leader in this field, refuses to license his encryption programs to foreign companies, he suddenly discovers that his company is the target of a hostile takeover bid whose stated purpose is precisely the liberalization of computer encryption. Gordian finds himself alone to defend the country's security. He will have to confront a dangerous coalition: a network of drug kingpins, corrupt military officials, and crooked politicians whose primary goal is to permanently eliminate him. Even if it means sacrificing world peace.
