Winner of a unique position among the wealthy and world-renowned. And she's a survivor, indomitable as her father, the man who returned from the edge of death to wrench a fortune in diamonds from the bleak South African earth. Now, celebrating her ninetieth birthday, Kate surveys the family she has manipulated, dominated, and loved: the fair and the grotesque, the mad and the mild, the good and the evil -- her winnings in life. Is she the... MASTER OF THE GAME?
