A LEGENDARY SUBURBAN BARBECUE. A SULKING HUSBAND. AND A CHARMING NEIGHBOR OFFERING FAR MORE THAN A TOUR OF HIS HOT TUB.

Sarah Brown only ran into her handsome new neighbor, Sam Patterson, at the Tesco ice cream aisle.

But one smooth conversation later, she finds herself holding an invitation to the infamous annual summer barbecue on Cornflower Close—a notorious, alcohol-fueled 48-hour marathon she's spent years trying to avoid.

This is the neighborhood event where remorseless hangovers are born and disastrous rumors are made. Literally everyone goes, including the enigmatic Mr. and Mrs. Crosbie from No. 4, who clearly operate under a very loose, very open marriage layout.

As dusk falls and the Aperol flows, the cracks in Sarah's own suburban life begin to show.

With her husband in sight, Sam corners Sarah with an irresistible proposition: a private, late-night tour of his brand-new hot tub.

But a midnight soak isn't the only thing Sam is offering... and before the night is over, Sarah is about to indulge in the most uninhibited, forbidden desires of her life.
