For an easy, breezy beach read, look no further than the works of Elin Hilderbrand—her latest is so evocative you can almost hear the sound of the waves and feel the sand between your toes. Set on the elite islands of Martha’s Vineyard and Nantucket, The Identicals follows twin sisters who, after years of estrangement, trade lives in order to save their relationship. Mistaken identity hijinks and plenty of romance ensue.
