Winn Van Meter is heading for his family’s retreat on the pristine New England island of Waskeke. Normally a haven of calm, for the next three days this sanctuary will be overrun by tipsy revelers as Winn prepares for the marriage of his daughter Daphne to the affable young scion Greyson Duff.

Winn’s wife, Biddy, has planned the wedding with military precision, but arrangements are sideswept by a storm of salacious misbehavior and intractable lust: Daphne’s sister, Livia, who has recently had her heart broken by Teddy Fenn, the son of her father’s oldest rival, is an eager target for the seductive wiles of Greyson’s best man; Winn, instead of reveling in his patriarchal duties, is tormented by his long-standing crush on Daphne’s beguiling bridesmaid Agatha; and the bride and groom find themselves presiding over a spectacle of misplaced desire, marital infidelity, and monumental loss of faith in the rituals of American life.
