Tom Callahan has written the seminal book on golfing great Tiger Woods. Woods who has gone out of his way to protect his privacy, has never allowed himself to get close enough to a writer to be properly examined on the page. And as a consequence, his fans know relatively little about him except what's divulged in quick tournament interviews or the scarce information passed out on occasion by one of his handlers. Callahan, commonly regarded as one of the best international all-round sportswriters, has followed Tiger around the world of golf for over seven years, enjoying a certain access to the man and his parents Earl and Kutilda Woods. His relationship with the family deepened whe he undertook a remarkable journey to Vietnam to learn the fate of the South Vietnamese soldier who was Earl Woods' best friend during the war - and his son's namesake. Tiger is a 20-year old when the book opens and 27 when it closes. During those years Callahan covered Woods at all the majors, including the Masters, the US Open, the British Open, culminating in Tiger's heart-stopping race to make history by clinching the string of Majors, affectionately nicknamed the Tiger Slam. As the pulse of the world of gold was measured by the curve of his swing, Tiger made everyone skip a beat as he attempted to win the Grand Slam a year later.
