No story has been more central to America’s history this century than the rise of Barack Obama, and until now, no journalist or historian has written a book that fully investigates the circumstances and experiences of Obama’s life or explores the ambition behind his rise. Those familiar with Obama’s own best-selling memoir or his campaign speeches know the touchstones and details that he chooses to emphasize, but now—from a writer whose gift for illuminating the historical significance of unfolding events is without peer—we have a portrait, at once masterly and fresh, nuanced and unexpected, of a young man in search of himself, and of a rising politician determined to become the first African-American president.
