Silver Girl by Elin Hilderbrand

Meredith Delinn has nowhere to turn when her husband, Freddy, is imprisoned for defrauding investors out of billions of dollars. Even though they've been estranged for a few years, Meredith's childhood best friend Connie agrees to let Meredith accompany her to Nantucket. Connie is having problems in her own life--she misses her husband, Wolf, desperately since he died of cancer and wishes she could mend the rift between her and Ashlyn, her only child. Meredith's sojourn proves difficult, since she's afraid she'll be recognized and be hounded by the press and angry people that believe she was an active participant in Freddy's misdeeds (even though she was in the dark). It becomes a waiting game to see if she'll be cleared of any wrongdoing and be able to move on. Luckily, a widower and an old flame come along to help lift Connie's and Meredith's spirits. In revisiting both women's lifelong friendship and marriages along with their daily summer routine, Hilderbrand has written another beach read that's hard to put down.
