Elin Hilderbrand sets A Summer Affair in Nantucket where she lives and delves into the underworld of the gossipy and scandalous town.
Claire has a problem with setting limits but from a distance seems to have the ideal life with a devoted husband, children and a talent for designing and making beautiful glass objects. When she agrees to chair a committee for the Nantucket social fundraising event of the year, her life unravels quickly and it doesn't take long to compare her charismatic and adoring co-chair to her husband who rarely utters more than one-syllable words from the couch while watching television. She is soon embroiled in an illicit romance.
