Annika thinks she's heading for a carefree twenty-fifth anniversary holiday to an exotic Ischia spa with her husband. When she goes to his home office to retrieve his passport, she finds a beautifully wrapped box in a drawer and assumes it's her silver anniversary gift. The shock comes when at dinner at the resort, her husband hands her a gift certificate instead. She's sure now the present is intended for a lover, mostly likely one of her three closest friends, members of her Swedish-American women's group. But, with which one is he having an affair?
While in Ischia, the engaging and enigmatic spa doctor takes an interest in her, and while Annika's husband searches for his lost iPhone, he takes her on sightseeing excursions. When he makes an unexpected discovery, their relationship deepens.
Back in Greenwich, Connecticut, her adolescent children create a temporary distraction, as Annika struggles with her suspicions, her family obligations and through continuing emails, her growing attraction to the doctor she left behind in Italy.
