I just completed Elin Hilderbrand's Barefoot a wonderful read.
Three women arrive at the local airport, observed by Josh, a Nantucket native home from college for the summer. Burdened with small children, unwieldy straw hats, and some obvious emotional issues, the women-- two sisters and one friend--make their way to the sisters' tiny cottage, inherited from an aunt. They're all trying to escape from something: Melanie, after seven failed in-vitro attempts, learned her husband was having an affair, and then discovered she's pregnant; Brenda embarked on a passionate affair with an older student that got her fired from her prestigious job as a professor in New York; and her sister Vicki, mother to two small boys, has been diagnosed with lung cancer. Soon Josh is part of the chaotic household, acting as babysitter, confidant, and, eventually, lover.
