Chapter 1

"I can't believe we're in England!" Serena said excitedly to her best friend, Blair Waldorf. Blair wasn't exactly thrilled to be there, with the painful fact that they were in England for school and had no time for touring, but it was better than being stuck at home with her annoying mother and her fat, ugly boyfriend with the worst fashion sense she had ever seen.

"Yeah, I know," Blair replied. She was rather annoyed with Serena, who was acting as though she'd completely forgotten that they were there for education.

"I bet all the guys at Hogwarts are really cute," Serena said, trying to cheer her friend up.

"I'm not in the mood right now, okay?" Blair snapped. "I'm sorry, Serena, but I'm just not having a good day."
"You're thinking about Nate, aren't you?" Serena said. Blair nodded. Serena sighed and put her arms around her best friend in a comforting hug.
"Listen, Blair. You'll meet tons of new guys who are all going to be totally gorgeous, and you'll fall in love and completely forget about Nate. Okay?"
"Whatever," Blair said grumpily. She really didn't care about other guys at all. She only wanted him.

"Hey look, we're here," Serena observed. "C'mon, let's get out of the limo." She opened the door for herself and Blair to climb out. The limo driver helped them with their luggage, and after Serena paid him, he drove away.

Five minutes later, Blair and Serena had arrived on platform nine and three quarters.

"Cute guy number one," Serena said as she saw a tall boy with brown hair and green eyes walk past them.
"Oh, shut up," Blair told her.

They followed the other students onto the train, although it took quite a while. Finally, they were able to board the train.

"Here's an empty one," Serena said, and she and Blair entered the compartment. They put their bags down beside them, and sat down on the comfortable seats.

"Finally, I get to read my new magazines," Serena said, and took them out of her bag. Blair didn't feel like doing anything. She sat there, and let her mind wander. She wondered what the school was going to be like, and if the teachers were nice, and what the dormitories were like. They probably weren't as nice as the dorms at the colleges back in New York, of course. She sighed in disappointment, and took out her pink mini ipod.

As soon as the song started, she heard someone knock on the door. She looked up, and saw a boy with dark hair and glasses standing outside. He was sort of cute, Blair decided. She got up, and opened the door for him.

"Yes?" She asked, putting on her best smile. The boy had stunning green eyes, she noticed, and his glasses weren't the nerdy type.

"Um, hello," the boy answered nervously. "I was wondering if my friends and I could join you? All the other compartments are taken."

"Sure. One second," Blair replied. She turned to Serena, who looked up from her magazine.

"Can he join us?" Blair asked. "He doesn't have anywhere else to sit."

"Of course!" Serena answered. "I don't mind."

Blair turned back to the boy, and smiled at him again. "Come in," she said. "Are your friends with you?"

"Yes," the boy replied. "They're right behind me."

Blair let all three of them inside, and they sat down. She saw a girl with beautiful brown curls, and a boy with shaggy red hair and freckles. The boy with the red hair gaped at her.
Blair smiled at him without even blinking. She was used to boys staring at her all the time.

"I'm Blair Waldorf," she introduced. "And this is my best friend, Serena van der Woodsen. We're both from New York."

"I thought I heard an accent," the boy said. "I'm Harry Potter."

"And I'm Hermione Granger," the girl next to Serena said.

"I'm...um..." the boy with red hair tried to speak, but he was so in awe of Blair that he seemed to have forgotten his name.

"Ron Weasley," the girl said for him. "Honestly!" She gave Ron a frown, who shrugged sheepishly and crossed his arms.

"Is this your first time in England?" Harry asked.

"Yes," Blair answered, "we literally just got here yesterday, so we haven't had any time to go sight seeing or anything."

"What's that?" Ron asked, staring at Blair's pink mini ipod. Blair gave him a funny look. Shouldn't he know what an ipod was? It's not like nobody used them in England.

"You're kidding, right?" Blair answered, as Serena giggled. "It's an ipod, of course."

"What does it do?" Ron asked, looking at it with a rather curious expression on his face. Blair couldn't believe what she was hearing. How could anyone NOT know what an ipod was used for?

"It's used for listening to music," Blair answered. "Why, do you actually not use them in England?"

"Don't mind him," Hermione said. "I'm a muggleborn too. We use them here. We just have different devices than purebloods."

"Oh, right," Blair replied, not really sure of what she was talking about.

After a long hour of talking, the train finally slowed down to a stop.

"We're here!" Serena said excitedly. "I've been waiting for this moment forever."

Blair rolled her eyes. Why was Serena always so goddamn positive about everything? All she wanted to do was stuff her face and then lie on her bed and fantasize about Nate, and then she would be happy. Too bad she still had another three hours to go before they could get some sleep.
