They Will Have to Die Now: Mosul and the Fall of the Caliphate by James Verini
James Verini arrived in Iraq in the summer of 2016 to write about life in the Islamic State. He stayed to cover the jihadis' last great stand, the Battle of Mosul, not knowing it would go on for nearly a year. This urgent, scalding, hallucinatory work of war reportage (Patrick Radden Keefe) takes the reader into the conflict against the most lethal insurgency of our time.
