HARRY POTTER AND THE MUGGLE'S DAUGHTER

Prologue:

Lily

HPHPHP

Fingering an old knut in her palm Lily Potter stood in the shadow of a great oak, silently watching. Above, a waxing gibbous moon – four days yet before it was full – washed the open ground between her and The-Most-Haunted-House-In-All-Of-England. The knut in her hand warmed and drew her attention to the Shrieking Shack. Someone had tripped her Perimeter Charm. Right on time, Remus, she thought as a shadow crept across the open ground and slipped inside the building. A grim smile flitted across her face. Her skill at charms was exceeded only by her potion's mastery. In the last twenty-five years Hogwarts had only graduated one student who even came close to her in that discipline.

Severus Snape, her childhood friend; the boy who had known why strange things always seemed to happen around her, the first person to understand her… The first boy she had kissed… her first love.

The boy who had betrayed her for the Dark Arts and her less than pure blood.

Life changed people; him, not for the better. Funny, that. She'd loved Severus almost from hello; James, she had hated. Now, it was the opposite. The arrogant, obnoxious pure-blood had grown to be gentle, kind and loyal. She couldn't love him more. So she'd married him. And now they had Harry; her and James' son. Beautiful, wondrous, adorable Harry James Potter. It made her insides melt just to think about her precious baby boy.

But these days even Harry couldn't keep her thoughts from the war raging around them and her arsehole first boyfriend for long. It was why she was here now, her blood boiling with barely suppressed rage. Her son was now threatened because the coward had become a Death Eater. The worthless little prick had overheard part of the prophecy. And he had told his Master. Because of him Voldemort knew about her son. The most dangerous, evil, Dark Lord in near a millennia wanted her son dead. Oh, sure Albus had said the wanker might go after Neville, the son of Frank and Alice Longbottom, instead. But she didn't believe it. Something deep in her soul told her it was Harry who would defeat Voldemort. And it was Severus who had led the Dark Lord to him.

Bastard!

More than one night she'd prayed their paths would cross. Her work as an Unspeakable had led her to create more than one new spell. Flaying seemed far too merciful to her mind.

She pushed off from the tree. With Silencing and Disillusionment Charms to rival those of Dumbledore himself, she made her way to the shack… It was time.

Remus turned as she entered the destroyed remains of the kitchen. "Hello, Lily."

She dropped her charms. Silence and near invisibility could not hide her from the enhanced nose of the werewolf. She eyed the first friend she had made after being sorted into Gryffindor. Quiet, studious, a loner, he was much like herself and they had become fast friends long before James, Sirius and Peter eventually learned his secret. She supposed it was having a werewolf as one of his best friends that helped James to shed some of his arrogance. Certainly his acceptance of Remus' condition went a long way towards her seeing he did have a great capacity for kindness.

"Remus," she answered.

He studied her for a second. This was not the kind of greeting that had become commonplace between them. "I got your message," he said. "You wanted to talk?"

She nodded. "I did."

"Why here? Why alone?"

Lily took a deep breath. "There's a spy in the Order."

It was just the tiniest bit but Remus seemed to collapse in on himself. "You think it's me," he said, his voice defeated. When she didn't answer he eventually met her eyes again.

"No," she said.

For a few moments all he could do was blink rapidly in response. "James?"

"He's not certain what to believe. Sirius either. Peter, he'll believe whatever those two tell him."

Remus nodded slightly. "Why are we here?" he asked.

"We're going into hiding," she answered.

"The Fidelius?"

"I cast it last week."

"Which would explain why I no longer know where you live," he answered. Lily smiled painfully. "I suppose it would be a vain hope that you are here to share the secret with me?"

"It would."

Remus turned away from her. "Thank you for telling me that much at least."

Lily waited a few seconds before answering. "I need you to be my backup plan."

Remus frowned. "Backup plan?" he asked, turning to her.

"My trust in the others is largely based on the opinions of James, Sirius and Albus. My trust in you is solely of my own convictions. My grandparents had a place near Bourton-on-the-Water. My parents left it to me. I'm going to place it under the Fidelius as well. I want you to be my Secret Keeper."

Remus frowned. "Are you telling me you don't trust Sirius?"

Lily shrugged. "I'm not telling you anything other than I don't believe you're the traitor and I need you to be my backup plan."

Remus considered her for another few moments. "When?"

Lily handed him a bit of parchment with the coordinates for the property. "Now."

Author's notes:

Well, there it is ;the beginning of my attempt to re-write the entire series. I hope this is an acceptable beginning that gets people intrigued. One thing I'll address right here.

Could Lily have cast the Fidelius? I tend to think so. From JKR's own work we know that Lily was a gifted student; particularly at Charms and at Potions. Let's remember Snape was modifying potions and inventing his own spells by his sixth year. Everything we are told about Lily is that she was the equal of James, Sirius, Remus and Snape. So if Snape can be modifying potions and inventing his own spells and James and Sirius and Peter, who we are led to believe is not really all that gifted, can become animagus, and with Lupin can create the Marauder's Map, then I feel it safe to say Lily can do similar difficult magic. And let's remember the motivating factor of protecting her family.
