The Couple in the Photo

Lucy and her husband, Adam, have been best friends with another couple, Cora and Scott, for years. The four are practically family-they vacation together, co-own a beach cottage, and their children are inseparable. So Lucy is devastated when, while looking at a colleague's photos of a trip to the Maldives, she spots a picture of Scott, apparently on vacation with another woman.
Then she learns that the woman in the photo has gone missing. Lucy can't help but fear that Scott was involved. But searching for answers might uncover secrets about Scott, Cora, and even her own husband that could destroy the picture-perfect lives they have built together. Or maybe she was never part of the picture at all. Is it possible everyone knows more than they are letting on? If so, what are the consequences of exposing the truth?
