2014. The Islamic State is unstoppable. Across Syria and Iraq, city after city has fallen beneath its black banner. Its warriors are killing children. Its warriors are taking slaves. Now the jihadists advance on Baghdad itself. If Baghdad falls, the entire Middle East will follow.
The world is utterly unprepared for this onslaught, and needs time to prepare a counterattack. To give Baghdad a chance, a retired American operative named Ambrose Hayes will launch the most daring mission imaginable: posing as a jihadist himself and attacking the Islamic State from within.
But joining the jihad and surviving it are very different things. As Hayes attempts to buy the world time, he must defeat three deadly opponents: a ferocious field commander, a diabolically cunning governor, and a merciless warlord known as the Angel of Death.
Prepare for a world of furious action and white-knuckle terror, as a veteran agent faces his greatest challenge. Stand with Ambrose Hayes as the noose tightens around him, and watch him battle onward in defiance of the horrifying truth: to defeat his enemies, he may have to die beside them.
