Against the backdrop of the most brutal conflict of recent decades, we chart the spymaster's struggle to develop the unit from scratch in challenging circumstances after the American invasion of Iraq in 2003, we follow the fraught relationship of two of his agents, the al-Sudani brothers - one undercover in ISIS for sixteen long months, the other his handler - and we track a disillusioned scientist as she turns bomb-maker, threatening the lives of thousands.
With unprecedented access to characters on all sides, Pulitzer Prize-finalist Margaret Coker challenges the conventional view that Western coalition forces defeated ISIS and reveals a page-turning story of unlikely heroes, unbelievable courage and good old-fashioned spycraft.
