Mallory starts to cry. Mallory alone in the family had maintained a relationship with Greta after Uncle Bo died. She wrote letters each month and secretly called every Christmas; she invited Greta to her college graduation over her parents’ objections; she had ridden four hours on the bus to spend those perfect weekends in Cambridge.

“Is this real?” Mallory asks Senior. “Greta is dead? She left me money and the cottage? The money and the cottage are mine? Like, mine-mine?” Mallory doesn’t want to sound like she cares more about the money and the cottage than about her aunt’s passing. But she also can’t ignore what might be a life-changing reversal of fortune.

“Yes,” Senior says.

When Leland returns from brunch, she has a Bellini glow; her skin actually appears peachy beneath the asymmetrical bangs of her new haircut. It takes Leland a moment to process what Mallory is telling her: After Mallory gives proper notice to the headhunting firm, she’s moving out. She’s going to Nantucket.

“I still don’t understand why you would leave the center of the civilized world to live on an island thirty miles off the coast,” Leland says.

It’s now two weeks later, Sunday, May 30. Leland is treating Mallory to a bon voyage brunch at the Coconut Grill on Seventy-Seventh Street. They’re sitting at an outdoor table on the sidewalk in the broiling sun so that they can be properly observed by the boys with popped collars and Ray-Ban aviators who are on their way to J. G. Melon’s for burgers and Bloody Marys. One such specimen—in a mint-green Lacoste—lowers his shades an inch so he can check out Leland. He looks like the Preppy Killer.

Leland sounds perplexed and also sad. The announcement of Mallory’s imminent departure promptly restored love and affection between the two friends. Over the past two weeks, Leland has been sweet. She not only tolerates the sight of Mallory’s messy bedding, she sits on the edge of the futon for long, gossipy conversations. And Mallory can absorb the changes taking place in her friend—the edgy haircut for starters, the leather jacket purchased for a whopping nine hundred dollars at Trash and Vaudeville, the switch from Bartles and Jaymes wine coolers to proper bottles of Russian River chardonnay—without feeling resentful or left behind.

Mallory and Leland will miss each other. They’ve been friends since before memory, having grown up three houses apart on Deepdene Road in the Roland Park neighborhood of Baltimore. Their childhood years had been idyllic: they biked to Eddie’s Market for jawbreakers; they listened to the Grease soundtrack on Leland’s turntable, stuffing their training bras with rolled-up socks and singing into hairbrushes; they sat in the Gladstones’ hot tub on snowy nights; they watched General Hospital after school in Leland’s rec room, playing hands of spit on the shag rug during commercials. They had been perfect angels until high school, when their shenanigans started. Leland’s father, Steve Gladstone, bought a convertible Saab when the girls were seniors. Leland had taken it without permission, swung over to Mallory’s house in the middle of the night, and thrown pebbles at Mallory’s bedroom window until Mallory agreed to go for a joyride. They’d put the top down and driven all the way to the Inner Harbor with the cassette player blasting Yaz’s Upstairs at Eric’s. They were caught, of course. When they arrived back to Deepdene Road, their hair blown crazy from the wind, all four of their parents were standing in the Gladstones’ driveway.

We’re not angry, they said. (This must have been Steve Gladstone’s influence; he was the most lenient of the four.) We’re disappointed.

Mallory had been grounded for two weeks, she remembers. Leland had been grounded too, but she got out of it after three days.

“I need to try something different,” Mallory says now as she dunks a sweet potato fry into the maple dipping sauce. “Set out on my own.” Besides, the center of the civilized world is already a cauldron, and it’s not even June; the concrete is baking, the trash can on the corner stinks, and there’s no place less hospitable than the platform of the 6 train. Who wouldn’t want to be headed to Nantucket for the summer? Or for forever?

Six weeks later when Mallory’s brother, Cooper, calls to say that he has proposed to Krystel Bethune, his girlfriend of three months, and they will be getting married at Christmas, Mallory is so intoxicated with her new island life that she forgets to be properly shocked.

“That’s great!” Mallory says.

“Aren’t you going to ask if I knocked her up?” Cooper says.

“Did you knock her up?”

“No,” Cooper says. “I’m just madly in love and I know I want to spend the rest of my life with Krystel, so I figure, why wait? Let’s get married as soon as we can. Within reason. I mean, I don’t want to elope. Senior and Kitty would kill me. As it is, they aren’t too happy.”

“Right,” Mallory says. “How’d you two meet again?”

“Krystel was my waitress,” Cooper says. “At the Old Ebbitt Grill.”

“Nothing wrong with being a waitress,” Mallory says. Mallory is waitressing herself at the Summer House pool out in Sconset three days a week. “Did she go to college? Like, at all?”

“She went to UMBC for a while,” Cooper says.

That’s vague, Mallory thinks. A while meaning a few semesters or a few weeks? It doesn’t matter. Mallory won’t judge; they have their mother for that. Kitty Blessing is downright obsessed with education, breeding, social standing.

“You’re getting married at Christmas,” Mallory says. This is a phenomenon she has never understood—Christmas is already so busy, frantic, and filled with angst; why make it worse?—but again, she won’t judge. “Where will it be?”

“In Baltimore,” Cooper says. “Krystel’s mother has no money and her father isn’t in the picture.”

Mallory tries to imagine her mother’s reaction to this news. Kitty has lost the war but won a crucial battle. Krystel’s family is a disappointment, so there will be no dynasty-building. However, that means Kitty will have no competition in planning the wedding. She’ll insist on tasteful Christmas (white lights, burgundy velvet bows, Handel’s Messiah) rather than tacky Christmas (elves, candy canes, “Jingle Bells”).

“I’m happy for you, Coop,” Mallory says. For what might be the first time in her life, she’s telling the truth about this. For all of her twenty-four years, Mallory has suffered from a chronic case of sibling envy. Cooper is the golden child to Mallory’s silver. He’s the chocolate chip cookie to her oatmeal-raisin, which people like, just never quite as much.

“So now’s the part where I ask you a favor,” Cooper says.

“Oh,” Mallory says. He wants a favor from her? This is new. Cooper is a policy wonk for the Brookings Institution, a think tank in DC. His job is important, prestigious even (though Mallory’s not going to pretend she understands what he actually does). What could he possibly need from her? “Anything for you, you know that.”

“I’d like to have a bachelor…well, not a party per se, but a weekend. Nothing crazy, just me, Fray, obviously, and Jake McCloud.”
