Ireland is as famed for its majestic golf courses as it is for its writers. In "Ancestral Links" we join one man - John Garrity, a writer for "Sports Illustrated" and "Golf Magazine" - as he returns to the northwest of Ireland (where his great-grandfather once left for America) that is now home to an unforgettable golf course. Part memoir and part travelogue, this is a book for golf enthusiasts and for all those who treasure Ireland's remarkable golf courses. Golfing has been an obsession in Garrity's family for generations, and this book tells of it how it has captivated and continues to hold the imagination of each of them. Penguin, $24.95.
