With a storm brewing in Bryn Mawr, Pennsylvania, the Killer WASPs head south to Palm Beach, Florida. And what could be better than fabulous friends, Lilly Pulitzer beachwear, frozen cocktails, and high-society drama?

Kristin Clark and her basset hound, Waffles, are ready to escape the doldrums of winter to bask in the warm Florida sun and dine at her friends' new restaurant, Vicino. But when a rival restaurant undergoes an HGTV makeover and attempts to steal Vicino's spotlight and its patrons, the town is abuzz with gossip, and Kristin and her friends—Bootsie, a nosy reporter; Holly, a chicken nugget heiress; and Sophie, the soon-to-be ex-wife of a mobster—have parties to attend.

Everything is going swimmingly in the glitz and glamour of Palm Beach until a bad batch of clams threatens to shut down Vicino and their vacation for good. When it becomes clear that the clams may be more than an innocent mishap, the ladies must unravel the mystery before there are deadly consequences.
