Nate and Liv have a great life together but they miss the spontaneity and freedom they enjoyed early on in their romance. Careers and their children have inevitably kept them busy, so when Nate discovers Liv is feeling disconnected from him, he plans an anniversary trip to the idyllic seaside town of Hartwell, Delaware. There he hopes they will have the opportunity they've been craving--a chance to reinvent themselves and fall in love all over again.

With each new day comes a new adventure, from wedding crashing at the five-star boardwalk hotel to pretending they are two strangers having a chance encounter at the boardwalk bar. In the midst of this daring, sexually- charged game of romantic rediscovery, Nate and Liv discover the only constant they need is each other.
