Welcome to Peachtree Bluff: a sweet, cozy small town where family is everything. The "go-to for elevated beach reads," (People), Kristy Woodson Harvey, returns just in time for pumpkin spice season.

The air is crisper, the water is calmer, but, when it comes to the Murphy family, nothing is ever quite as simple as it seems.

Youngest sister Emerson is busy planning her dream wedding to Kyle. But her difficulty expanding her family is overshadowing her joy. Pregnant middle sister Sloane and her husband Adam's dream house has turned into a nightmare. Everything is over time, over budget, and Sloane is over it. Eldest sister Caroline, as always, is there to swoop in and get her sisters' lives under control. Until her focus is more than a little shifted by Emerson's hunky costar who manages to sweep her right off her feet?just as her not-quite-ex-husband decides it's high time he begged Caroline for a second chance.

Matriarch Ansley and her new husband Jack have finally hit their stride. But when a scandal that would affect every single Peachtree Bluff citizen comes to light?and it seems like Jack just might be at the center of it?Ansley questions whether he is actually the man she thought he was.

Through it all, these women must rely on their powerful family bonds, and the quirky characters and small-town charm of the place that, no matter what, always calls them home.
