Tom Clancy Under Fire

Jack Ryan Jr. stands alone against powerful enemies in this thrilling novel in Tom Clancy's #1 New York Times bestselling series.

On a mission in Tehran, Jack Ryan, Jr. , meets his oldest friend, Seth Gregory. As they part, Seth slips Jack a key, along with a perplexing message. The next day Jack is summoned to an apartment where two men claim Seth has disappeared with funds for a vital intelligence operation. They say he's turned and leave Jack with a warning: If you hear from Seth, call us. Do not get involved.

Jack soon finds himself lost in a maze of intrigue, lies, and betrayal where no one is who they seem to be-not even Seth, who's harboring a secret that harkens back to the Cold War. A secret that is driving him to the brink of treason. . . .
