A frontline witness account of the deadly urban combat of the Battle of Mosul told by former Navy SEAL and frontline combat medic Ephraim Mattos.

After leaving the US Navy SEAL teams in spring of 2017, Ephraim Mattos, age twenty-four, flew to Iraq to join a small group of volunteer humanitarians known as the Free Burma Rangers, who were working on the frontlines of the war on ISIS.

Until being shot by ISIS on a suicidal rescue mission, Mattos witnessed unexplainable acts of courage and sacrifice by the Free Burma Rangers, who, while under heavy machine gun and mortar fire, assaulted across ISIS minefields, used themselves as human shields, and sprinted down ISIS-infested streets-all to retrieve wounded civilians.

In City of Death: Humanitarian Warriors in the Battle of Mosul, Mattos recounts in vivid detail what he saw and felt while he and the other Free Burma Rangers evacuated the wounded, conducted rescue missions, and at times fought shoulder-to-shoulder with the Iraqi Army against ISIS. Filled with raw and emotional descriptions of what it's like to come face-to-face with death, this is the harrowing and uplifting true story of a small group of men who risked everything to save the lives of the Iraqi people and who followed the credence, "Greater love hath no man than this, that a man lay down his life for his friends."

As the coauthor of the #1 New York Times bestselling American Sniper, Scott McEwen has teamed up with Mattos to help share an unforgettable tale of an American warrior turned humanitarian forced to fight his way into and out of a Hell on Earth created by ISIS.
