“Omigod,” Gracie said, looking at her sister, “I’m never going home.” Victoria smiled, and they held hands as the driver spun them through the free-form traffic around the Arc de Triomphe, and they headed back down the Champs-Élysées again, toward the Seine, saw the view of the Invalides, which housed Napoleon’s tomb, and sped across the Pont Alexandre III, onto the Left Bank. They were staying at a tiny hotel Victoria had heard about, on the rue Jacob. They were planning to travel as inexpensively as possible, stay in small hotels, eat in bistros, and go to galleries and museums. They were on a tight budget for a trip both girls knew they would remember all their lives. It was an incredible gift from Victoria to her sister.

They had onion soup that night at a tiny bistro around the corner from their hotel. After dinner they walked around the Left Bank, and then came back to their hotel and went upstairs and talked until they fell asleep. Gracie had been getting text messages from her friends at home from the moment she turned her phone on at the airport, and they continued long into the night.

The two girls had croissants and café au lait in the lobby of the hotel the next morning, and then they set out on foot to go to the Rodin Museum on the rue de Varenne, and from there to the Boulevard Saint-Germain, bustling with activity, where they had coffee at the venerable old artists’ restaurant, Aux Deux Magots. And after that they went to the Louvre and spent the afternoon there seeing famous treasures.

Gracie wanted to see the Picasso Museum, which they did the next day. They had dinner in the Place des Vosges, which was one of the oldest sections of the city, in the Marais. And after that they rode on a Bateau Mouche, all lit up on the Seine.

They saw an exhibit at the Grand Palais, walked in the Bois de Boulogne, visited the lobby of the Hotel Ritz, and walked down the rue de la Paix. They both felt as though they had walked all over Paris in the five days they were there. They had seen everything they wanted to by the time they left for London, and they were just as energetic there. They went to the Tate Gallery, the Victoria and Albert Museum, and Madame Tussaud’s Wax Museum in the first two days. They saw the crown jewels in the Tower of London, the changing of the guard at Buckingham Palace, visited the stables and went to Westminster Abbey, and walked down the grandeur of New Bond Street, looking into all the expensive shops they couldn’t afford. Victoria had treated herself to an expensive handbag at Printemps in Paris, and Gracie went wild with T-shirts and funny jeans in the King’s Road in London, but they had both been very well behaved, and spent their money wisely. At night they had dinner in small restaurants, and they stopped at sandwich shops in the daytime. They managed to do and see everything, and their parents checked on their progress daily, mostly, Victoria knew, because Gracie was with her, and they said they missed her.

They had been gone for almost two weeks when they flew from London to Venice, and their pace slowed dramatically once they were there. Their arrival at the Grand Canal was breathtaking, and Victoria paid for a gondola ride to their hotel, while Gracie lay happily in the boat and looked like a princess. The moment they arrived in Italy, every man in the street was looking at her, and when they walked around Venice, several times Victoria noticed men following them and staring at her younger sister.

They walked through the Piazza San Marco, and bought gelato, went into the church itself, and wandered endlessly for hours along the narrow winding streets, in and out of churches, and when they finally stopped for lunch, Victoria ordered an enormous bowl of pasta and ate it all. Gracie had picked at hers and said it was delicious. She was too excited to eat much, and it was hot. They hadn’t stopped moving for a minute. And they both agreed afterward that Venice was their favorite city. They did more walking, eating, and relaxing there, moving at a slower pace, and they spent hours at outdoor cafés just watching people. Gracie insisted on buying a tiny cameo brooch for their mother, which wouldn’t even have occurred to Victoria, but she had to admit that it was very pretty, and a very sweet gesture. They bought a tie for their father at Prada, and silly souvenirs for themselves. There was a gold bracelet that Victoria fell in love with in a shop near the Piazza San Marco, but she decided she couldn’t afford it, and Gracie bought a music box shaped like a gondola that played an Italian song neither of them knew.

Their days and nights in Venice were absolutely perfect. They visited the Doge’s Palace, and every major church in their guidebook. They took a gondola ride under the Bridge of Sighs, and hugged as they glided underneath it, which supposedly meant they would be together forever, although the promise was only meant for lovers. But Gracie insisted it applied to them too. And for their one elegant evening, they went to Harry’s Bar, where they ate another enormous meal. The food in Venice was fantastic, and Victoria ate risotto or pasta with delicious sauces at every meal and tiramisu for dessert. This wasn’t about comfort food, it was about exquisite Italian cuisine, but its effect on her body was the same.

They both hated to leave and fly to Rome for the last leg of the trip. They did more walking, shopping, and visiting churches and monuments there. They visited the Sistine Chapel, took a tour of the Catacombs, and wandered around the Colosseum. And they were both exhausted but happy by the end of the trip. It had been as unforgettable as Victoria had hoped, and a moment in their lives and a memory that she knew both of them would cherish forever. They had just tossed a coin in the Fountain of Trevi and found their way to an outdoor café on the Via Veneto, when their father called them. He couldn’t wait for them to come home, and Gracie sounded excited to see him too. They were planning to fly from Rome to New York. Gracie was going to spend two days with her sister in New York, and then fly back to L.A. on her own. Victoria had promised to come out to help her settle into the dorm in August, but she had no plans to spend time in L.A. this year. Her life was in New York now, and she knew that Gracie would be busy with her friends before they all went their separate ways for college. It was a relief for Victoria not to spend two or three weeks living with her parents. She wanted time to relax in New York.

On the flight from Rome to New York, they talked about everything they’d done and seen. And Victoria was relieved that there hadn’t been a single bad moment on the trip. Gracie had been a pleasure to be with. And although their views of their parents were very different, Victoria was careful not to dwell on it. They talked about other things. And Gracie had thanked her profusely for the incredible trip. They were halfway to New York when Gracie handed her a small package wrapped in Italian gift paper, with a little green ribbon. She looked mysterious and excited when she gave it to her big sister, and thanked her again for the fabulous trip. She said it was the best graduation present in the world.

Victoria opened the package carefully, and felt something heavy inside it. It was in a soft black velvet pouch, and when she opened it, she saw the beautiful gold bracelet she had fallen in love with in Venice, and had decided not to buy herself.

“Oh my God! Gracie, that’s crazy!” The generosity of the gift took her breath away, and Gracie put it on Victoria’s wrist.

“I bought it with my allowance and the money Dad gave me for the trip,” her sister told her proudly.

“I’m never taking it off,” Victoria said as she leaned over and kissed her.

“I’ve never had such a great time in my life,” Gracie said happily, “and I probably never will again. I’m sad that it’s over.”

“Me too,” Victoria admitted to her. “Maybe we can do it again sometime, when you graduate from college.” She smiled wistfully. That seemed like a lifetime away right now, but Victoria knew how fast the years would fly by from now on. It seemed like only yesterday when she had graduated from high school, and now she was twenty-five and her college graduation was three years behind her. And she knew it would happen just as fast for her younger sister.

They talked for a long time on the flight, and then finally drifted off to sleep. They both woke up as they were landing in New York. It was sad to think that the trip was over. The time together had been magical, and they looked at each other and smiled nostalgically as they landed. They were both thinking that they wished they could start the trip all over again.

It took them an hour to get their bags and get through customs, and another hour to get into the city in a cab. By the time they pulled up in front of Victoria’s building, Rome, Venice, London, and Paris felt like they were a lifetime away.

“I want to go back!” Gracie said mournfully as Victoria let them both into the apartment. It was a weekend, and everyone was away, and they had the place to themselves.

“So do I,” Victoria said as she read a note from Harlan, welcoming her home. He had left some groceries in the fridge so she could cook Gracie breakfast. And Victoria put their bags in her bedroom. It felt strange coming home.

They went to bed early that night, after calling their parents to say that they had arrived safely. Gracie was always good about that, and didn’t want them to worry. She had never gone through a rebellious phase and sometimes Victoria wished she had. It might have been healthier than being so close to their parents. She hoped that now Gracie would find some independence in college, but she had a feeling they’d be wanting her to come home all the time. It made Victoria glad that she had gone to Northwestern, but they had never been as attached to her. And Gracie was their baby.
