Widow Cassie Merrill wants to move on, she really does. A hundred percent. Okay, maybe eighty percent. Four years after her husband leaves "involuntarily," a vacation to Crete with her best friend Bea seems like the perfect remedy to jumpstart her life. At the beach on their first day, Bea––always a sucker for a good head of hair––forms an attachment to a local hottie. She then pairs the reluctant Cassie with his tagalong cousin Stavros as a fourth for a too-cozy dinner. Not interested at first, Cassie knows that until she pushes past her old memories and fulfills the vow made to her husband, she will never move forward. Fighting FOMO––Fear of Moving On––she honors her pheromones and accepts Stavros' invitation to have lunch at his favorite beach, Legaria, drink a little retsina and swim in the Mediterranean. Despite his charming facade, Stavros has a case of the post-divorce blues he can't shake, and a young son with problems. Cassie's attention is a balm for his spirit and soul, and for the first time in a long time, Stavros fears for his heart. Cassie battles her rising panic. With Stavros' kindness and energy and bossy yet loyal Bea egging her on to let go of the past, Cassie just might find romance again. Will their love affair last longer than one Hot Greek Summer?
