"Years ago, during a certain summer in Maine, two young women, unaware of each other, met a charismatic man at a craft fair and each had a brief affair with him. For Jane it was a chance to bury her recent pain in raw passion and redirect her life. For Susie it was a fling that gave her troubled marriage a way forward. Now, sixteen years later, the family lives these women have made are suddenly upended when their teenage girls meet as strangers on social media. They concoct a plan to spend the summer in Maine with the man who is their biological father. Their determination puts them on a collision course with their mothers, who must finally meet and acknowledge their shared past and join forces as they risk losing their only daughters to a man they barely know."--Publisher description.
