**A *New York Times* Notable Book of 2020 ** **“[A] sweeping and authoritative history *(*** ***The New York Times Book Review *),* * ***Black Wave *****is an unprecedented and ambitious examination of how the modern Middle East unraveled and why it started with the pivotal year of 1979.** Kim Ghattas seamlessly weaves together history, geopolitics, and culture to deliver a gripping read of the largely unexplored story of the rivalry between between Saudi Arabia and Iran, born from the sparks of the 1979 Iranian revolution and fueled by American policy. With vivid story-telling, extensive historical research and on-the-ground reporting, Ghattas dispels accepted truths about a region she calls home. She explores how Sunni Saudi Arabia and Shia Iran, once allies and twin pillars of US strategy in the region, became mortal enemies after 1979. She shows how they used and distorted religion in a competition that went well beyond geopolitics. Feeding intolerance, suppressing cultural expression, and encouraging sectarian violence from Egypt to Pakistan, the war for cultural supremacy led to Iran’s fatwa against author Salman Rushdie, the assassination of countless intellectuals, the birth of groups like Hezbollah in Lebanon, the September 11th terrorist attacks, and the rise of ISIS. Ghattas introduces us to a riveting cast of characters whose lives were upended by the geopolitical drama over four decades: from the Pakistani television anchor who defied her country’s dictator, to the Egyptian novelist thrown in jail for indecent writings all the way to the murder of journalist Jamal Khashoggi in the Saudi consulate in Istanbul in 2018. *Black Wave* is both an intimate and sweeping history of the region and will significantly alter perceptions of the Middle East.
