Bobby Jones, the Grand Slam and Mark Frost
Mark Frost's The Greatest Game Ever Played was surely one of the most breezy, fun golf reads in recent memory. I know some (like the fine gang on Golfclubatlas.com) don't care for his take on history (or his occasional error), but I find Frost's narrative style to be compelling. He's got a new book out on Hyperion called Bobby Jones: The Grand Slam and it is another interesting read. I'll post more once I've finished it, but it certainly contends with James Dodson's recent bio of Ben Hogan as the best golf book I've read in the last year.
Anyway, check more out on Frost at his home page.
