I am very happy to say that Cassiopeia Malfoy and my other OCs are my own personal creations. Most everything else belongs to JK Rowling :)

AN: This fic is going to cover Lily Luna Potter's years 3-7 at Hogwarts, so it's gonna be pretty long. My main reason for writing this is the terrible lack of HP femslash around here. Granted, the slash will come later, but it will be here, as will other relationships. The main character's 13 now though, so be patient.

Right now I'm going through to fix the section breaks that got deleted, and fixing typos and deleting outdated author's notes as I do it.

Chapter One: Back to Hogwarts

"Bye Lily, bye Albus, bye James," said Ginny fondly as the Potter family gathered on Platform 9 ¾.

"We'll see you for the Christmas Holidays," said Harry, ruffling Lily's and Albus's hair.

Albus pulled a face.

"Dad! I'm not a kid anymore."

"Have a good time, and behave yourselves," Ginny looked meaningfully at Albus. He gave her his most innocent look.

"Bye mom, bye dad," said Lily, giving each of her parents a kiss.

"Hey, there's Scorpius," said Albus. "Catch you later."

"Those two are as thick as thieves," said Lily's mother, laughing.

"And about as troublesome," said her father shaking his head.

"Because you never caused any trouble when you were at school," said Ginny teasingly.

Lily scowled. In her opinion, Scorpius Malfoy was the biggest prat in the world. He was always leading her brother into trouble and treated her as if she were about five.

"You'd better get on the train," said Lily's father. "It's about to leave."

Lily waved to her parents one last time and then hurried toward the train. As she got on, her friends Marica and Dawn beckoned to her from the first compartment.

"Hey," she said, stowing her trunk overhead and then sitting down across from her friends.

"How was your summer?" said Dawn, blowing her long brown bangs out of her eyes.

"Oh, same old, same old," said Lily, shrugging. "How about you?"

"Mum took us to America," said Dawn, grinning. "We went to Disney World. I have pictures, see?" She pulled out a large stack of photographs. Most of them were of people wearing funny costumes, giant metal constructions, or Dawn and her little brother eating all manner of sugary sweets. Dawn's excitement was obvious even in the stationary Muggle photos.

"Looks like fun," said Lily. "I'm jealous."

"It was great!" Dawn gushed. "Have you ever had cotton candy? It's the best thing EVER."

Lily laughed. Dawn had the biggest sweet tooth in the third year.

"What about you, Marica?" said Lily.

"Mum's family visited," said Marica, rolling her eyes. "Mum made me wear long skirts and a headscarf the whole time."

Marica's mother's family was Muslim.

"How does this even fit under a headscarf?" said Dawn, pulling at Marica's frizzy black curls.

Marica stuck her tongue out at Dawn. All three girls laughed.

"Lily?"

Lily looked up. Her cousin Hugo stood in the doorway.

"Hugo!"

When Lily and Hugo were little they had been inseparable, but ever since they had started school and Hugo was Sorted into Slytherin while Rose was Sorted into Gryffindor they had started to grow apart. Lily missed him.

"Lily, have you seen Al?" said Hugo.

Lily sighed. She should have known.

"No. He went off with Scorpius Malfoy before we got on the train."

Hugo looked disappointed.

"Why don't you come and sit down?" said Lily. "There's plenty of room."

Hugo looked over his shoulder, as though expecting Albus to appear in the corridor, but when he didn't Hugo said, "Sure."

Lily scooted over on the seat to make room for Hugo.

"So, are you looking forward to Hogsmeade?" said Marica, leaning back in her seat.

"Definitely!" said Lily and Hugo together.

Dawn squealed and bounced up and down on her seat. "Am I ever!" she exclaimed.

"What d'you think'll be the best part?" said Lily.

"Honeydukes!" said Dawn at once, smacking her lips.

"The Three Broomsticks," said Marica.

"Zonko's," said Hugo. "Al and Scorpius are always coming back with cool stuff from there. How about you, Lil?"

"I don't know," said Lily. "I'm looking forward to it all!"

*****BWST*****

When the Hogwarts Express pulled up at Hogsmeade Station several hours later, the four third years left their compartment and joined the throng heading toward the horseless carriages that would take them up to the castle.

"Look, there're Al and Scorpius!" said Hugo, pointing toward Lily's brother and his best friend. "See you later, Lil."

"Pathetic," muttered Lily, shaking her head in mild disgust as she, Dawn, and Marica climbed into a carriage.

A moment later they were joined by River Thurshall, a tall, muscular Ravenclaw fourth year.

"Hi, Lily," he said, sitting down beside her.

"Hi River," said Lily.

"How was your summer?"

Lily shrugged. "Fine. How about yours?"

"It was good," said River, "but I'm glad to be back at school. With all my friends."

"Yeah," said Lily. "Me too."

River looked Lily up and down. "You look taller," he said. "Did you grow over the summer?"

"Yeah," said Lily. "I think so."

"What new classes are you taking this year?" asked River after a moment.

"Care of Magical Creatures, Arithmancy and Muggle Studies," said Lily.

"Professor Cornan gives pretty tough work," said River. "If you ever need help with Arithmancy..."

"I think I'll be okay," said Lily. River's face fell slightly. "Thanks though."

"Any time," said River.

As the three girls walked up the stone steps and into the castle, Marica hit Lily on the arm.

"Hey! What was that for?"

"Lil, you can be so oblivious sometimes!" said her friend.

"What are you talking about?" said Lily.

"River!" said Marica. "Couldn't you tell he was totally hitting on you?"

Lily laughed. "Yeah, right. What would River be hitting on me for? We're just friends."

"He wasn't looking at you like he wanted to be just friends," said Dawn teasingly.

"You're crazy," said Lily

"If it were me," said Marica, "I would not be complaining. River got hot over the summer. Plus, he's a fourth year."

Lily just rolled her eyes. "Whatever. Let's hurry up and get to the feast, I'm starving."

The three friends continued into the Great Hall and plopped themselves down a the Gryffindor table right as Professor Bloomfield, the Charms teacher and Deputy Headmaster, was bringing the Sorting Hat onto the stage.

"Hey," said Lily. "The first years must have gotten across the lake extra fast this year.

"Yeah, well, the weather's really good today," said Marica.

"Whatever the reason, I'm not complaining," said Dawn. "That means we'll get to eat sooner." She hunched over and swung her long arms like a caveman. "Dawn want food!"

Lily and Marica laughed. Marica swatted Dawn on the arm. "Moron," she said.

Dawn stuck her tongue out at her.

"Shhh!" said Lily. "The Sorting's starting!"

The Great Hall fell silent as the tear near the brim of the hat opened wide and the hat began to sing.

I bet you all are wondering,

How it is a hat can speak,

But I'm the Hogwarts Sorting Hat,

And that makes me unique.

I'm not at all like other hats,

That you might go out and buy;

Stick around for just a bit,

And I will tell you why.

Long, long ago, when this school began,

The founders, they decided

To each create a house with their

Most treasured students inside it

To do this job, once they were gone,

The founders they made me,

Just plop me down upon your head,

To see what I may see.

Gryffindor is for the brave,

Courageous against danger;

And Hufflepuff is for the just,

Whose devotions never waver;

Those Ravenclaws are quick of wit,

And keen to pursue learning;

While those in Slytherin are sly,

And keep ambition burning.

So I am here to tell you just

In which house you belong.

And to introduce myself,

I have prepared this song.

And now you know, what I am for,

And what I'm doing here.

So step up front, and slip me on,

I'm a good hat, never fear!

And once I'm sitting on your head,

And take a nice good look,

I shout the house that's best for you,

And say: See? That's all it took!

"Oooh," said Dawn. "I liked that one. I think it was the best yet!"

"Dawn, you said that last year," said Marica, laughing.

"Yeah, but this one was ever better!" said Dawn.

"Hush!" said Lily.

Professor Bloomfield stood up and said to the first years, "When I call your name you will come here, put the Sorting Hat on your head, and sit down on the stool. When the hat calls out its decision you will join your new house's table. Abbot, Jeremy!"

The small, nervous boy approached the stool and sat down gingerly, lowering the hat onto his head. The hat paused for a second and then called out, "HUFFLEPUFF!"

Lily watched with mild interest as the rest of the first years were sorted into houses. She didn't know any of this year's new students, so she was only half paying attention when Professor Bloomfield called out, "Malfoy, Cassiopeia."

Lily looked up. "Malfoy?"

"Yeah," said Marica. "Scorpius's little sister."

"Malfoy has a sister?"

Marica raised her eyebrows. "You didn't know that? Malfoy and your brother are best mates."

"Yeah well, I try to have as little to do with Malfoy as possible," said Lily, wrinkling her nose.

Lily turned her attention back to the Sorting. The Malfoy girl was just sitting down on the stool. She was small, possibly the smallest first year there, and the hat completely hid her thin face. Lily expected the hat to call out "SLYTHERIN!" as soon as it touched her head, but instead the hat was silent.

The girl fidgeted. The hat was taking a long time to decide, longer than Lily had ever seen it take before. Finally, after over a minute, the tear near the brim opened and the hat shouted, "GRYFFINDOR!"

"What?" said Lily. She wasn't the only one; all around the Great Hall people were exchanging shocked glances. The Malfoy family had been in Slytherin for as long as anyone could remember. It would have been one thing for the girl to be sorted into Ravenclaw, though even that would have been surprising, but Gryffindor?

The small girl got up off the chair, took off the hat, and walked quickly over the Gryffindor table and sat down.

"How did a Malfoy end up in Gryffindor?" said Dawn, oggling at the newly arrived blond.

"I dunno," said Lily, shrugging. "But I'm betting her brother won't be too pleased."

*****BWST*****

After the feast ended and the Headmaster had made all the announcements, Lily, Marica, and Dawn, feeling full and more than a little sleepy, got to their feet and headed into the entrance hall. As Lily was about to start up the marble staircase she heard Albus's voice call her name.

"Hey! Lil! Wait up!"

Lily turned around and saw Albus and Scorpius coming toward her. The crowd parted before them like the red sea.

"Yeah?" said Lily to Albus, pointedly ignoring Scorpius. "What is it?"

"This is my little sister Cassiopeia," said Scorpius, tugging forward the small girl, whom Lily hadn't noticed was standing behind him. "She was Sorted into your house. Into Gryffindor."

"I know what my house is thanks, Malfoy," said Lily coldly. "And I saw her being Sorted."

"Say hi, Lily," Albus prompted.

Lily narrowed her eyes. She hated the way Scorpius talked to her; as though she were about five years old. And she hated even more the way that Albus started treating her like a kid too whenever he was with Scorpius.

"Hi," said Lily shortly.

"Cassiopeia doesn't know anyone in Gryffindor yet," continued Scorpius.

"So we thought that you could look after her," said Albus.

"You know, be her friend, show her around," added Scorpius.

"No way," said Lily. "I'm not going to babysit your little sister, Malfoy."

"Aw, come on, Lil," said Albus. "It's just until she gets used to being at Hogwarts."

"No," said Lily.

"Don't be such a sourpuss, Lily," said Albus in annoyance. "She's Scorp's sister," he added in a calmer voice. "You know I'd want somone to do the same for you if your were sorted into a strange house."

Lily huffed. "Alright fine. I'll show her around for a couple of days. But's that's it okay?"

"Thanks, Lil," said Albus.

"Yeah, thanks kid," said Scorpius, ruffling her hair.

She glared at him. "Sod off, Malfoy, I not doing this for you. Come on," she added to the little girl.

Cassiopeia Malfoy just stood there, staring at the floor.

"Let's go," said Lily. "Gryffindor Tower is this way."

When the girl still didn't move or look up, Lily took her hand and, rolling her eyes, led her up the marble staircase.

"Pay attention to where we're going," she told the younger girl. "I'm not going to be your permanent castle guide."

*****BWST*****

"This is the Fat Lady," said Lily crossly when they finally reached the entrance to Gryffindor Tower. She had practically had to tow the girl along; she would swear she was dragging her feet on purpose. "You have to tell her the password. What is it again? Rose told me at dinner—oh yes, Beatlenut!"

The portait swung forward and Lily pushed the smaller girl into the Common Room.

"Here we are, Gryffindor Common Room." She swept her arms around the room expansively. "Home sweet home. The girls dorms are up here. Come on."

Lily led Cassiopeia to girls' staircase. When they reached the first landing, Lily pointed to the door on the left. "There you are. First year dorms." Then she turend on her heal and continued to the third year dorms.

Marica, Dawn, and their fellow Gryffindor third years Tamzen Guthrie, Brandi Formans, and Paloma Cartrez looked up when Lily came through the door.

"Where've you been?" said Dawn, rolling a lolipop around in her mouth. "We thought you'd been abducted by aliens or something."

"Not unless you think Albus and Malfoy are aliens, which isn't out of the realm of possiblity," said Lily, flopping down on her bed and pulling off her shoes.

"What did they want?" said Tamzen, glancing up from the latest issue of the Quibbler.

Lily huffed in annoyance. "They've somehow conscripted me to play nanny to Malfoy's little sister. They think she needs someone to 'show her around' and 'be her friend'. I'll tell you what, I may have concented to show her around for a couple days. But I am not going to be her friend. The kid's eleven and about half my size. And she didn't say two words to me all the way up here. In fact, I don't think she even siad one word."

"Aw, come on," said Brandi, rolling over to look at Lily. "Why don't you give her a chance?"

"I'm giving her a chance," said Lily. "I agreed to help her settle in, didn't I? I assure you, I'm not doing it for Scorpius Malfoy."

"I wouldn't mind doing something for Scorpius Malfoy," said Tamzen slyly.

Lily shuddered.

"Let's go to sleep," said Paloma from the corner. "I'm half asleep already."

"Me too," said Marica, yawning.

Lily pulled her nightgown over her head and slid under the covers. Marica flicked her wand to douse the lights.

"'Night girls," called Dawn sleepily, as she she had every night at Hogwarts since their first year.

"'Night," the other five chorused. And, exhausted from the excitement of being back at Hogwarts, they were all soon asleep.

AN: I know, the chapter title is lame. They get better, mostly.

Also, don't get me wrong, I love Al and Scorpius, but for this fic they had to be a bit obnoxious.

I enjoy reviews, even on older chapters like this one, but if you don't review I won't hunt you down :)
