A journey through the fault lines of contemporary religious wars US-born Protestant evangelicalism has gone global to an extent of which many of us might be unaware. This book tells the story of Americans’ colossal mobilization to proclaim Christianity “to the ends of the Earth,” a movement that triumphed in the Global South, challenged the Vatican, then turned east in full force after 9/11 to spread the Gospel among Muslims. When the wars in Afghanistan and Iraq set off a wave of anti-American attacks and made the field too dangerous for US missionaries, thousands of disciples, particularly from Latin America, were mobilized to finish the task. In Soul by Soul, journalist Adriana Carranca follows the pilgrimage of a missionary family from Brazil as they move to Afghanistan. Carranca brings us on a harrowing journey through the underground passages of the global evangelical movement as it clashes with the full force of militant Islamic groups in the Middle East and South Asia, where contemporary religious wars are being fought, soul by soul. “A stunning achievement of both immersive reportage and rigorous research.... This is an extraordinary book.” —Eliza Griswold, Pulitzer Prize–winning author of Amity and Prosperity
