Without any kids to look after, Eliza and Mara spent the entire time perfecting their tans and discovering new shopping streets. On Wednesday they hit the Saks in Southampton, Thursday was the Tanger Outlets in Riverhead, and on Friday they bought matching vintage Lilly Pulitzer dresses at Colette. They were also spending a lot time with the boys. Eliza and Jeremy had explored the vineyards on the North Fork, and Mara had been taking surf lessons from Ryan, sans Camille, thank goodnessFriday night Ryan called a house meeting in the hot tub.“So I was thinking . . . it’s about time we had a little party,” Ryan said, grinning from behind the bubbles. “You know, just a small party—only close friends,” he suggested.“That sounds awesome!” Eliza cheered.“Sure, it sounds like fun.” Mara nodded.“Okay, so tomorrow night, then. Mara, you’ll come with me to get the food. Eliza, you have the best ID, so I’ll put you in charge of the booze. And Jacqui, hey, where the hell is Jacqui?”
