This is an untypical political biography in that there is no index, nor footnotes to cross reference the author's findings. Admittedly the author accepts that his approach was different.
It really is a story of three of the Kennedy bothers - John, Robert, and Edward, with the emphasis on Edward. It starts at the assassination of John on through the assassination of his brother, and onto the mystery of Chappaquiddick.
It touches on Edward's schooling and marital problems, but the book is really about the Kennedy brothers in the sixties.
At times it is over sentimental, although critical of Edward Kennedy.
It also pre-supposes that John was assassinated by the Mob, and that this affected Robert and Edward in their initial lack of determination in going for the Presidency.
It's an easy read and fanciful at times. If it's a light read you're after then it's okay. If you like political biography, or you are a serious Kennedy watcher, then don't buy it.
