Tamim Ansary was born in Kabul, Afghanistan, and came to the United States as a junior in high school. Culture and cultural perspective have been among his lifelong preoccupations. His new book, The Invention of Yesterday, looks at world history as the story of ever-increasing human interconnectedness: history from the perspective of the emerging global "we". Ansary has also written a history of the world through Islamic eyes, a history of Afghanistan from an insider's point of view, a literary memoir about straddling a cultural fault line in the world (Islam and the West), a historical novel set against the background of the First Anglo-Afghan war, and some 30 nonfiction books for children. In Road Trips, he tells the story of morphing from an Afghan into an American just as the sixties were giving way to the seventies. His Destiny Disrupted won the Northern California Book Award for nonfiction in 2009, and his first memoir West of Kabul, East of New York was selected as a One City One Book pick by both San Francisco and Waco, Texas. In 2001, an email he sent to 20 friends reputedly became the first viral phenomenon of the Internet Age, reaching tens of millions around the world within days.
