This story is kind of an attempt to revive my (extremely) old story "Harry Potter and the New Marauders" that I wrote several years ago and currently makes me want to cry. Yes, it's that bad. I've been working on this since OotP (the book) came out, so I hope everyone likes it!

Disclaimer: I don't own Harry Potter, just the original characters featured in the fic.

Thanks for reading!

Unable to sleep, Harry sat up. On the other side of the room, his friend Ron was snoring lightly into his pillow. The moonlight shifted through the ruddy curtains and drifted lazily over the room. Harry's eyes wandered once again to the photo by the side of his bed, the photo that Hagrid had given him a few days before. Putting on his glasses, he grabbed it and gazed at it for the hundredth time. He watched as his parents exchanged loving glances and smiles. They looked so happy to be there together, so happy to be surrounded by their friends and comrades. They turned their gaze out, their eyes seemingly comforting Harry in his time of trouble, though he knew it wasn't really so. Harry scanned the photo again, his eyes glancing over Frank and Alice Longbottom, who stood strong and proud in the front row. The Longbottoms looked so happy; if only they'd known what fate was in store for their future. Sirius and Professor Lupin, also beaming, stood close to Harry's parents. Sighing, Harry watched the four of them playfully nudge one another and laugh, their happiness forever captured in that euphoric moment.

Suddenly, something caught Harry's eye. There was someone else in the photo, someone new. This person, a woman, stood by Lily at the edge of the picture, barely in view, almost as though she were trying to hide. Her hair was dark and long, and it hung in a most unflattering manner around her face. She seemed worn and tired, as though she'd not slept in weeks. Her face was thin and appeared rather sad. The clothes she wore were dark and heavy. Harry watched his mother as she turned to the mystery girl and nudged her in the side. The woman smirked, then, at the urging of both Lily and James, began to smile awkwardly She looked uncomfortable in her surroundings, like she didn't want to be there.

Harry was certain that she had not been there when Moody had named off the members in the photo. He did not know who she was, or where she'd been, but there was something strangely familiar about her, something he felt he'd seen before, he'd known before, he'd spoken with before. He knew, however, that he had never even laid eyes upon that woman before that moment. He needed to know her name, where she was – was she still working for the Order? Where was she now?

Baffled, Harry got up and, careful not to wake Ron, sneaked out of the room, taking the picture with him downstairs, desperate to find out who the woman was - or had been. He reached the front hall, making sure to sneak quietly past the portrait of Sirius' mother, and looked around. At that time of night, he hadn't expected to find many others awake, but a light towards the end of the hall indicated that someone indeed was. Harry softly crept down the corridor, praying that the light was not just due to Kreacher's late night ramblings. He opened the door to find Remus Lupin sitting at the long table, his nose buried in a rather thick Hermione-esque book; a chocolate bar not far out of reach.

"Professor - ?"

Remus looked up from his book, "Harry. Still awake at this hour?"

"I couldn't sleep."

"I can't blame you." he replied, "As you can see, I've had some trouble sleeping as well."

"Could I ask you a question?"

"Of course." Remus answered, closing his book. Harry walked over and sat next to him. He placed the old photograph onto the table before his former teacher.

"I'd forgotten about this." Remus said with a smile.

"Who is this girl?" Harry asked, pointing to the mystery figure at the edge of the picture, "When Mad-Eye gave me this photograph, she wasn't there. I've no idea who she is, but there's something about her - something familiar."

Remus leaned over for a better look. It did not take him long to identify her. By the looks of it, he had known her very well. He leaned back, his smile suddenly gone from his face; "I have not seen her for some time."

Harry looked at the girl in photo, her dark eyes looking away from the camera. Harry followed her line of vision - it led to Remus. Harry looked up at his old professor, who seemed a little reluctant to elaborate on the matter.

"I can't imagine why she'd seem familiar to you, Harry." Remus said quietly, his eyes watching the girl, "She went to school with us – your father and I. She appeared out of nowhere in our fourth year, and then disappeared after sixth year. I didn't see her again until well after we had all left school, about the time this group came together. She was a good friend of your mother's. Skilled as she was, she was a complete mystery to those who knew her."

"What do you mean?" Harry asked, confused.

Remus looked at Harry, then back at the photo, "It's late, Harry. You should be trying to get some sleep."

Picking up the picture, Harry stood and headed for the door. Looking at the girl once more, he stopped and looked at his old professor, "You were also friends with her, Professor, weren't you?"

Remus nodded slightly; "At least, that is what I thought."
