Chapter 1

Unexpected Arrival

"Why doesn't Lily notice me?" moaned James. Sirius, Remus, and Peter sighed.

"I don't know, mate, just about every other girl does" replied Sirius, bringing his bottle to his lips and taking a swig.

It was their first night back at Hogwarts for the start of fifth year, and after a long and boring summer apart, they were celebrating their reunion in the Shrieking Shack. Sirius had even managed to get his hands on some alcohol, and the four boys were all planning on becoming righteously trashed.

"Damn" said Sirius. "We should have invited Lily along and gotten her drunk! That would have been so funny!"

"I wish we had invited a couple of girls, you're right" agreed Remus "I think-" He stopped mid-sentence, and cocked his head to the side. "Can you hear that?"

The boys all stopped what they were doing to listen. At first they could hear nothing, but then they heard a strange whirring sound, that seemed to be coming from the corner of the room. Suddenly, a gust of wind swept through the room, and a shape seemed to appear out of nowhere, transparent at first, but growing steadily more solid with each whir.

"What the devil!?" yelped Peter. "What kind of magic is this? Sirius, are you doing that?"

"SHH! No I'm not doing that. What is it?" Sirius sounded very confused, but Peter still refused to believe that the bright blue telephone box that had appeared out of nowhere in the Shrieking Shack was real.

The whirring stopped, and the boys held their breath as the door to the telephone box opened slowly. Out stepped two girls, who looked cautiously around the room then nodded and smiled at each other. One girl was dark-skinned and pretty, with mischievous brown eyes, so dark they were almost black, and a tangle of black curls that could rival Sirius's cousin Bellatrix. She immediately strode across the room and settled herself on a very startled Remus's lap.

"You said you wanted girls and here we are! Isn't anybody going to offer me a drink?" she said, like appearing out of nowhere in a bright blue telephone box the middle of the night in the Shrieking Shack was no big deal. "I'm Ellie, by the way."

James hurried to grab another bottle from the small esky on the floor beside Sirius's chair, and handed it cautiously to Ellie. She seemed harmless enough, and having some girls here would definitely be more fun.

Sirius was still staring curiously at the second girl, who was shaking her head at Ellie, and receiving a sly wink in return, as Ellie wrapped her arm around Remus's neck and brought her bottle to her lips.

This girl was tall, much taller than her friend and the other three boys. Maybe even taller than Sirius himself! Her brown hair was in two plaits, and her blue eyes darted nervously around the room, taking everything in as she stood awkwardly in the doorway of the telephone box.

"And your name is..?" inquired Sirius. The girl wasn't pretty, exactly, but she looked like the type of girl who could be fun once you got to know her, and Sirius wanted her to come and talk to him.

She cleared her throat, and said quietly "I'm Meg"

"Here" said Sirius, patting the seat beside him. "Come sit down."

Meg seemed to consider the offer for a few seconds, then walked awkwardly over and perched herself on the edge of the seat.

"Um, hi" it was almost a question, and Sirius smiled at how nervous she was.

"You want a drink?" he asked, holding up a bottle. He still had no idea who these girls were or where they came from or how they appeared here, but he wasn't going to worry about it too much. They were here, and that was all that mattered for now.

"Huh? Oh, um, no thanks" said Meg ruefully. "I don't drink."

Sirius shrugged and put the bottle down, then started asking her about herself, and soon they were having a proper conversation, and she relaxed a little.

Peter was still staring wide-eyed at these two girls who seemed have made themselves right at home here without asking. Sirius was laughing at something Meg was saying, and Remus seemed to be making a move on Ellie, and soon the two were snogging. James caught Peter's eye from the other side of the room, and the two of them shared a confused look, then James shrugged and went back to his thoughts about Lily. Peter retreated further into his corner. He didn't trust the girls, and wasn't going to talk to them.

"Peter, mate, have another drink!" Sirius tossed him a bottle, then skulled the last of his own. "Gettin' in there, Moony!" he laughed, then noticed how strangely quiet his other friend was being. "You okay, James?"

James shook his head slightly as though to clear it, and sighed. "Yeah, I'm fine. I just wish Lily would pay me some attention, that's all. But she's so caught up with Snivelly Snape that she doesn't even notice me at all."

Sirius felt for his friend, but he was starting to get fed up with this constant obsession with Lily Evans. She was beautiful, that was true, but tonight was meant to be a chance for the guys to have some fun, not to sit around moping about girls they couldn't have. He rolled his eyes. "James, mate, forget her and have another drink."

Ellie looked over at James and said wisely "'Love isn't fair, so there you are, love."

Meg looked up and caught Ellie's eye and a silent message passed between them.

"Sorry boys," said Meg, standing up. "You're going to have to excuse us for a second; we have something we have to do."

And with that, both girls disappeared back into the telephone box. There was a second or two of confused silence in the room, and then the telephone box disappeared with the same strange whirring noise as before. The four boys stared at the spot where it had been.
