The Teeth of the Tiger

When his back's against the wall, the President turns to secret intelligence agency the 'Campus'.  And to operative Jack Ryan, Jr . . .
Just  before Jack Ryan stepped down as US President, he created a secret organisation designed to operate in areas where the CIA and FBI couldn't go - able to use any  and all means to neutralise terrorists who threatened America.
Now his son, Jack  Ryan, Jr, is part of that organisation and he's on the front line when a group  of Islamic terrorists backed up by Colombian drug smugglers, strike at the heart  of American society. With no conventional way to hit back at the shadowy  ringleaders, it's left to Jack Ryan Jr to take on the terrorists the only way he  knows how . . .
