When terrorists destroyed the Twin Towers on September 11, 2001, former New York City Police Commissioner Bernard B. Kerik was at the scene within moments. In the ensuing months, he helped Mayor Rudolph W. Giuliani coordinate rescue efforts and rebuild a shattered city, reassuring all Americans with his quiet strength and leadership. But September 11 was only the most visible in a series of extraordinary challenges Kerik has faced. From the tough streets of a New Jersey town to Colombia's cocaine fields, from Rikers Island to New York City, Kerik has dedicated his life to fighting injustice -- as a jail warden, beat cop, decorated undercover narcotics detective, and commissioner of the largest municipal police force in the world. But his most personal battle came when he pursued the greatest unsolved case of his life -- the tragic mystery of his mother, who abandoned him more than forty years ago. This is his astonishing, touching, and ultimately inspiring story.
