An exile in a strange country, Janya Kapur has left her wealthy, close-knit Indian family for an arranged marriage to a man she barely knows. Plainspoken Wanda Gray is tired of watching her marriage fail, so she takes a job guaranteed to destroy it—if her husband cares enough to discover what she's doing. Since her daughter's death, widow Alice Brooks has grown forgetful and confused. Her son-in-law and granddaughter have come to stay, but Alice isn't sure she's grateful.When the only other resident of Happiness Key dies alone in his cottage, the four women warily join forces to find his family. Together, they discover difficult truths about their own lives and the men they love—and uncover the treasure of an unlikely friendship.
