Tom Clancy's Op-Center: Call to Treason is yet another gripping addition to the bestselling series masterminded by Tom Clancy and Steve Pieczenik. The Op-Center's budget is slashed, leaving General Mike Rodgers in the market for a new job. When presidential candidiate Senator Donald Orr recruits Rodgers to act as his military advisor, it sounds like a perfect transition. There's just one problem.

But he's soon offered a job by a dynamic senator making a run for president as the head of his own third party. The only problem is that the senator's campaign is beginning to acquire a body count.
