In the aftermath of the 9/11 attacks, a Sikh-American mistakenly seen as Muslim was murdered in a "retribution" killing. Valarie Kaur, then a 20-year-old college student, traveled across the United States to document stories in Sikh, Muslim, and Arab-American communities. Over the next five years, her project expanded to include interviews with Americans from a wide range of religions and all walks of life, as well as scholars, law professors, and legislators. Divided We Fall places these stories into the larger context of American history, politics, and society. It raises important questions about "who counts" as an American.
