Sorensen returns to January 1953, when he and the freshman senator from Massachusetts began their extraordinary professional and personal relationship. Rising from legislative assistant to speechwriter and advisor, the young lawyer from Nebraska worked closely with JFK on his most important speeches, as well as his book Profiles in Courage. Sorensen encouraged the junior senator's political ambitions—from a failed bid for the vice presidential nomination in 1956 to the successful presidential campaign in 1960, after which he was named Special Counsel to the President.

Sorensen describes in thrilling detail his experience advising JFK during some of the most crucial days of his presidency, from the decision to go to the moon to the Cuban Missile Crisis, when JFK requested that the thirty-four-year-old Sorensen draft the key letter to Khrushchev at the most critical point of the world's first nuclear confrontation. After Kennedy was assassinated, Sorensen stayed with President Johnson for a few months before leaving to write a biography of JFK. In 1968 he returned to Washington to help run Robert Kennedy's presidential campaign. Through it all, Sorensen never lost sight of the ideals that brought him to Washington and to the White House, working tirelessly to promote and defend free, peaceful societies.

Illuminating, revelatory, and utterly compelling, Counselor is the brilliant, long-awaited memoir from the remarkable man who shaped the presidency and the legacy of one of the greatest leaders America has ever known.
