On March 24, 2021, ISIS fighters attacked the small coastal town of Palma in northern Mozambique. Men and equipment that could have come to the town's rescue and the fuel they needed were just a few minutes away in one of the world's largest natural-gas fields, but that rescue never materialized: More than 1,000 people were killed, and yet somehow the story was missed by the outside world. In propulsive prose, Polk Prize winner Alex Perry chronicles the minute-by-minute action to heartbreaking effect while vividly portraying the people involved: the domineering CEO of one of the largest energy corporations on the planet, the vengeful rebel leader bent on a bloodbath, and those who heroically fought to survive the onslaught, from a pro diver-turned-remote site contractor to a Mozambican mediator determined to save hundreds to local villagers who subsequently experienced a second horrific assault months later. Blood Will Flow is the riveting account of a deadly terrorist attack, a toxic mix of greed and fossil fuel extraction, and a stirring story of the survivors' fight for justice.
