This is the story of the friendships that defined one of America's most beloved Presidents. Chris Matthews, who has been following and studying the Kennedys most of his life, has interviewed President Kennedy's closest confidants - family, friends, and those who served with him--to create a moving portrait of a man many loved but few really understood. These friends were with Jack Kennedy as he took surprising risks, struggled with chronic illness, and repeatedly confronted "the thin membrane between life and death." As Matthews describes it, Jack Kennedy was a rebel, an adventurer, and a great enjoyer of life precisely because he understood its fragility. Being with Jack Kennedy was great fun for his friends. Now readers will share in that experience.
