There are three new cookery-lifestyle-entertaining books out with South Fork connections and they couldn’t be more different from one another. One is a new paperback printing of Ellen Wright’s “Hamptons Weekends,” originally published in 2000. Another is “Living the Good Long Life” by Martha Stewart, described as “a practical guide to caring for yourself and others.” Lastly, is “What’s a Hostess To Do?” by Susan Spungen, part of a series with other such titles as “What’s a Golfer to Do?” and “What’s a Disorganized Person to Do?”
