If there's one thing Jack Ryan, Jr., learned from his father, it's that freedom isn't free, but nothing can prepare Jack for the price he must pay in this electrifying entry in the #1 New York Times bestselling series. Jack Ryan, Jr., is in a world of trouble. When a benign surveillance operation takes a deadly turn, Jack finds himself locked in a struggle with an unseen enemy bent on destroying The Campus. The chase leads Jack to the South China Sea, where a midair collision between aircraft from rival nations threatens to serve as a flash point for the entire region. As Jack frantically tries to put the pieces of the conspiracy together, The Campus is hit with a crippling attack. When the dust settles, Jack is one of the few operators still standing and The Campus's de facto leader. But the fight is just beginning. As tensions escalate, Jack's mysterious adversary executes a brilliant campaign to paralyze the American government, while China inches closer to invading Taiwan. With the odds stacked against him and no help in sight, Jack and his shattered team must stop the world's two remaining superpowers from stumbling into war, even as the noose around The Campus grows ever tighter. Every operation has a cost. This time, the bill might just be too much to pay.
