"Prongs! Padfoot! Wake up!" Sirius heard the yell and instantly knew it was Moony, but why was he calling them? Today was the first day of the Christmas holidays. He and Prongs had to stay at Hogwarts this Christmas because Prongs' parents – his parents – were busy with work from the Order of the Phoenix. Moony had elected to stay, too, so he could keep them company. Wormy's parents had wanted him to come home with them, so he hadn't stayed.

"Go away, Remus," he muttered. Suddenly, a jet of icy water enveloped him. He jerked his eyes open and jumped up, yelling,

"What the hell, Remus!" Moony wasn't paying attention. He had already turned to Prongs and had done the same thing. Looking around, it took him only a second to realize he wasn't in the dorm. In fact, this place didn't look like Hogwarts at all. How had they got here? James had jumped out of his bed, yelling, but neither of the two other boys cared. Prongs soon realized why they had been acting like that.

Padfoot raced over to the door and tried it. It was locked, of course. When was anything ever easy? All three boys reached for their wands simultaneously, only to realize they weren't there. What had happened? Their wands were gone; they had no idea where they were… This was a mess.

"Prongs, Moony? Do either of you know what happened?" Sirius said slowly, trying to stay calm.

"No idea, Sirius," Remus said, his eyes scanning the room.

"I don't know, Pads," Prongs replied. Moony moved around the room, looking for anything to give them a clue of what had happened. There wasn't much. Two sofas and a couple plushy armchairs were centered in the room. There was a book sitting on the armchair. Moony picked it up and froze. Seeing his reaction, the two Marauders rushed over just as Remus asked,

"James, do you have a relative named Harry?" Surprised by the apparently random question, Prongs frowned before answering,

"Not that I know of. Why?"

"Look at the title of this book," Moony said, pushing it into Prong's hand. Padfoot looked over his shoulder at the book. It was titled 'Harry Potter and the Sorcerer's Stone'.

"Let's read it!" Sirius exclaimed. James chuckled at the thought of Sirius willingly reading a book. Padfoot realized what he was thinking and defended himself,

"I read every once in the while! Just not while I have any other things to do…" Moony snorted,

"Yeah, like breathing." Sirius grinned back, unfazed by the comment.

Suddenly, there was a flash of light. Three people thudded to the floor. All three leapt to their feet, reaching for their wands. None of them had a wand with them. The three Marauders stared at the new company, and it took them a minute to realize one was Severus Snape, the other was Lily Evans, and the third was Regulus Black.

"What happened?" Lily demanded, glancing wildly around. The two Slytherins were glaring at the three Marauders. "Potter! Did you do this!"

"No!" James defended, "All three of us just woke up in here!" Suddenly Moony gasped as another flash of light happened, and a small, slight red-headed girl appeared. She seemed to be around Regulus' age, so a year younger than the Marauders.

"Who are you?" Snape demanded, narrowing his eyes at the newcomer.

"Call me Luna," the girl said cheerfully, not looking surprised, "Sorry 'bout taking you out of Hogwarts."

"W – what do you mean? We aren't in Hogwarts?" Remus questioned. Luna shook her head in an excited manner,

"Nope but don't worry, you'll go back eventually. First, however, you have to read a few books."

"And why do we have to do that?" James inquired, sounding slightly harsh. It was clear he was completely shocked.

"Because they're from the future, and I was sent here to help you change it. Check the publish date on the book if you don't believe me." Moony picked up the book and checked the date before exclaiming,

"Sweet Merlin's underwear! 1997." Luna stifled a giggle while the other's stared in shock at her and the book.

"I don't believe you," Snape declared firmly.

"Oh really?" Luna asked, smirking evilly, "You are a half-blood and go by the title Half-Blood Prince because you are proud to be half a Prince. Your father hates magic and you. In your fifth year you called Lily a mudblood and aren't friends anymore. Also in your fifth year, Sirius tells you how to get under the willow, and James has to save you from a werewolf under it." Snape's expression turned from impassive to angry as she stated half the facts from his life. He nodded curtly at her, telling her that he did believe her.

"Okay!" she said with a smile, "Let's start reading!" She handed the book to Sirius, who groaned,

"Why do I have to read it?" Lily smacked him lightly on the shoulder and she said,

"Just read it!"
