Afghanistan, 2022.

You can check out any time you want.
But you can never leave.

Two decades ago, the United States invaded Taliban-controlled Afghanistan to fumigate a rat's nest of international terrorists. And then it left.

Now the Taliban are teetering on the edge of a fresh civil war, and a new breed of militants is growing out of the fertile ground of chaos. One group makes the Taliban regime look like kindergarten teachers by comparison. It's known as Islamic State Khorasan. Brutal, violent, and bent on using the failed state of Afghanistan as a launching pad for global mayhem.

If there's one thing Trapp has learned, it's the more things change, the more they stay the same. IS-K has to be stopped.

The problem is, not everybody agrees...
