Over the course of a lifetime of service to his country, Colin Powell became a national hero, a beacon of wise leadership and, according to polls, "the most trusted man in America." From his humble origins as the son of Jamaican immigrants to the highest levels of government in four administrations, he helped guide the nation through some of its most heart-wrenching hours. Now, in the first full biography of one of the most admired men of our time, award-winning "Washington Post" journalist Karen DeYoung takes us from Powell's Bronx childhood and meteoric rise through the military ranks to his formative roles in Washington's corridors of power and his controversial tenure as secretary of state.
