"Miles Markell is missing, and everyone is a suspect. To the guests at The Harmony Resort, Doctors Miles and Grace Markell appear to be a perfect power couple. They run a couples therapy retreat in a luxurious resort in the Mayan Riviera where they help spouses deal with their marriage struggles. Johanna and Ben's relationship looks great on the surface, but in reality, they're deeply alienated from one another. Shell and Colin fight constantly (Colin is a workaholic, and Shell always comes second). As both couples begin Harmony's intensive therapy program, it becomes clear that Harmony is not all it seems--and neither are Miles and Grace. What are they hiding, and what price will these couples pay for finding out? As a powerful hurricane descends on the coast, trapping both the hosts and their guests, secrets are revealed, loyalties are tested and not one single person--or marriage--will ever be the same. A gripping exploration of relationships and trust, bestselling author Marissa Stapley delivers a propulsive read that reveals all the little lies we hide, even from ourselves."-- Provided by publisher.
