She embarked on a rock-star-style book tour to promote “Becoming” in more than 30 cities in the U.S., Canada and Europe.

The book traces Mrs. Obama’s upbringing on the South Side of Chicago, her academic and professional careers, her marriage to Barack Obama, the 2008 presidential campaign and the election that made the Obamas the first black U.S. president and first lady.
