True faith and allegiance
(Book)

After years of facing international threats, President Jack Ryan learns that the greatest dangers always come from within. Deadly events involving American military and intelligence personnel occur all over the globe, and it becomes clear that there has been some kind of massive information breach and that a wide array of America's most dangerous enemies have made a weapon of the stolen data. With U.S. intelligence agencies potentially compromised, it's up to John Clark and the rest of The Campus to track the leak to its source. Their investigation uncovers an unholy threat that has wormed its way into the heart of our nation.
