Disclaimer: I don't own Harry Potter

A.N. This story will most likely have slow updates, because I'm in the middle of a crossover story, but this idea popped in my head and I wanted to she how well the story would do. I've gotten into reading stories of Harry's kids lately and their mostly about Albus or James, so I wanted to do one with Lily, and I wanted to make Dudley have a kid that had magic. I've seen stories were he has a kid with magic, but I hope this one is different.

Chapter One: The Dursley's 21 years later.

Sage Dursley sat the last box of her things down in the old shed of her grandparents, Petunia and Vernon Dursley. Sage's life had just took a turn for the worse. Her mother Jane Dursley, had dead a few mouths ago. And after taken a little time off work her dad (who was a famous boxer) would soon be returning to the ring, so he had sold their house and moved them all into his parent's place. He won't be home most of the time and his parents said they would look after them when he was away; which was just fine with her older sister Zinnia who they adored and spoiled, but Sage was hated by her grandparents for no reason at all. They sneered at her when she came into a room, and yelled at her for no reason, and only gave her clothes for her birthday and Christmas, (Which always looked as if they came from a second-hand store) while they gave Zinnia, Laptops, I-pads, I-pods, and whatever else she wanted. They spent a lot on Zinnia just to keep her happy. They even bought her an I-Phone once, and she break it a week later, and of course blamed Sage and she got in trouble for it.

"Sage, sweetheart." Her dad's voice called. Sage ran out of the shed and toward his voice.

"There you are." He smiled at her. He was a tall man, had some pretty good size muscles where he worked out, and was a little chubby. She had his blue eyes, but her mom's thick wavy burgundy hair, that fall down past her waist, which annoyed her grandmother to no end, which is the main reason she kept it so long.

"Yes, Daddy." Sage asked. Her dad had to be Sage's favorite person in the world; when she was little he told her bedtime stories so she could fall asleep at night. Her favorite was one he told her many times, about a little orphan boy, name Harry who lived under the stairs and grow up to save the world from an evil wizard known only as He-Who-Most-Not-Be-Named.

"Your grandmother wants you sweetie." Dudley told his youngest daughter. Her smile immediately dropped. "I'm going to go get you some paint for your room. What color do you want?"

"How about light blue." Sage said. Her favorite color was blue. Dudley nodded.

"Zinnia wants pink." He made a face and Sage giggled. "Go on now. See what she wants." Sage gave her dad a hug and ran off into the house. And through the living room that was full of pictures of Zinnia, and only two pictures of Sage. One was a picture of her and Zinnia at the beach, she was about five, Zinnia was six, the other was a family picture of Sage, Zinnia and their parents, taken right before Sage's mother got sick.

"About time." Petunia Dursley said to her granddaughter when she saw her. "I'll show you what room you get." Petunia turned and walked up the stairs. "No one has stepped foot in it for over twenty years." Her grandmother stopped at the first door on the landing there was an old rusty padlock on it, and a smell piece of wood was nailed to the bottom of the door. It took Petunia nearly half an hour to get the lock off it a had rusted so bad. "We locked it up right after we got back."

"Back from where?" Sage asked.

"Don't ask questions." Petunia snapped. "You'll have to clean it out. Throw everything in there away, do not keep anything. " She jerked the door open. "I'll bring you the cleaning supplies." Without another word Petunia turned and left. After taking a deep breath Sage went into her new room.

Sage's eyes widen. Her grandmother hadn't been kidding when she said no one had stepped foot in here for over twenty years. The dust on the floor was ankle-deep. Cob webs covered ever corner and the ceiling. An old twin bed that sat against the wall was covered in dust. An old trunk stood open cobweb covered the inside and out, along with a few spider webs, with spiders, a few rotten, and moldy clothes was spilling out, them too covered in webs. Over in one corner was a stack of old books covered in dust and falling apart. The other corner had more old rotten clothes. A desk in front of the window had stacks of old news papers and covered in dust and cobwebs, and spiders. The curtains was moth-eaten and closed. The peach color paint was fading and peeling off the walls. The room it's self had a moldy smell to it.

Sage sighed this room was going to take forever to get clean, and she had to clean it before any of her stuff came out of the shed. It just wasn't fair; Zinnia got to have their dad's old bedroom. He would be sleeping in the guest room when he was here. Sage walked across the floor toward the window making dust stir and she sneezed, and eyes watered. She opened the curtains so she could raise the window, only to see it was boarded up from the outside. With an old rotten piece of wood.

"Here's the cleaning things." Petunia was back and sat the cleaning supplies in the doorway but didn't come in. "Remember everything in this room goes in the trash. And don't ask question about anything in here, don't even pay attention to it, just pick it up and throw it away, got me?"

"Yes, grandma." Sage said. Petunia nodded. "Did you use to have a cat?" On this side of the door Sage saw that the little board hammered to the other side of the door was covering up a cat flap.

"What?" Petunia asked, confused at her granddaughter's question.

"You have a cat flap on the door. So did you have a cat?" Sage asked again.

"I said not to ask questions." Petunia snapped and walked off toward the stairs. Sage stared after her grandmother for a minute, before grabbing the broom leaning against the wall and went back in the room, and begin to swip trying not to breath in the dust, as she tried to swip it up. But all it did was make the dust stir and float around. Sage sneezed again and her eyes was watering so bad it looked as if she was crying.

"It's going to be so fun living here." Sage mumbled.

She soon gave up swipping and grabbed a trash bag and begin to throw things away. She went to the corner to throw away all the old rotten moldy clothes. Which she found some odd ones. Under all the very large ragged clothes was weird robs of scarlet and gold, that had faded and were rotten and moth-eaten. (through she couldn't figure out how moths got in here) and some that looked like they were some kind of sports uniform. Sage shook her head at them before tossing them in the trash. She worked for over an hour, throwing things away. She took the covers and sheets off the bed and tossed them, she then cleaned all the webs off the walls, cleaned the window, took down and threw away the old curtains.

When she got to the desk, Sage picked up the very first paper and blow the dust off the front. But it had faded too much to read, so she threw it in the trash along with the rest of them. She then went over to the trunk and started cleaning what was in it out. First she cleaned off the cobweb, then she grabbed all the old rotten clothes and tossed them away. She glanced down in it and saw a book laying there. She picked it up and blow the dust off. It didn't seem to be in too bad of shape. And her eyes widen as she read the cover.

"A History of Magic." Sage read frowning. What was a book like this doing at her grandparents. Then another thought came to her mind. Who's room was this anyway. Who did all this old junk once belong too. She knew it wasn't her dad's old stuff. Her grandma would have never let it get into this shape. She opened the front cover and wiped some off the dust off the first page with her hand. Written under the words: This book belongs too, was the name Harry Potter. Sage closed the book, and ignoring her grandma's orders, she laid the book down next to her to keep; instead of throwing it away. She then went back to cleaning out the little bit that had been in the trunk. Beside the book she found: a cauldron, rolls of weird paper she was pretty sure was called parchment, some weird-looking feather pens, she couldn't remember what they were called, and ink bottles fall and empty. She kept the pens, cauldron, and ink bottle that was full, but threw the other stuff away.

When she was done with the trunk she went back to cleaning the stuff up off the floor again. She found a note under the desk written in that weird parchment paper. She unfolded it and read.

Dear Harry,

If it is convenient to you, I shall call at number four, Privet Drive this coming Friday at eleven p.m. to escort you to the Burrow, where you have been invited to spend the remainder of your holidays.

If you are agreeable, I should also be glad of your assistance in a matter to which I hope to attend on your way to the Burrow. I shall explain this more fully when I see you.

Kindly send your answer by return owl. Hoping to see you friday,

I'm, yours most sincerely,

Albus Dumbledore.

Sage giggled at the name then put the letter in here pocket, she would ask her dad who this Harry Potter was and how come he lived here with them, but she'll have to make sure her grandparents wasn't around when she asked. She then giggled again thinking about the weird name at the bottom of the letter. Maybe her dad could tell her who he was too.

"Laughing to yourself." A voice said, from the open doorway, she didn't have to look to see who it was. "I always knew you were crazy."

"Go away, Zinnia." Sage told her sister. Zinnia was just a year older than she was, so she just turned twelve and was a minnie Petunia Dursley. With blonde hair, and blues eyes, and was nothing but bones with horse like teeth. She was wearing jean cut off shorts and a pink top. Her blonde hair was cut short just up past her shoulders. She wasn't only like her grandmother in looks, she was also nosey, and her favorite pass time was to pick on or hit on her little sister, when she wasn't nosing in other people's lives.

"Look at your clothes their covered in dust." Zinnia cried, pointing at her sister. "You'll need two baths just to get clean."

"Zinnia, I'm busy go away." Sage said. Picking up the last by the desk and lifting up the old matters and putting it up against the wall.

"You should see a mirror." Zinnia laughed again. "On second thought no, the poor thing might break if you look into it."

"If I look in it." Sage cried, turning around from trying to lift the box springs from the bed to face her sister. "I'm not the one that looks like an anorexic horse."

"You little brat." Zinna picked the dust pan up off the floor and threw the dust that had been in it on Sage. She dead laughing when her sister was now covered head to toe in dust.

"Thats what you get, dusty." Zinnia laughed. "Or should I say Cinderella."

"Don't call me that." Sage cried, trying to dust off her hair.

"Whats going on in here." Dudley demanded, coming into the room, he was carrying two cans of light blue paint and a store bag full of paint brushes and pans. He set it all down next to the cleaning stuff and looked at Sage who was covered in dust to Zinnia and the dust pan that was still in her hand.

"Nothing, daddy." Zinnia said, tossing the dust pan back on to the floor.

Dudley still looked from Zinnia and Sage suspiciously, then sighed. "Zinna, grandpa has started painting your room, why don't you go help him."

"Sure, daddy," Zinnia said, then gave her dad her "I am-a-good-girl-look. Then skipped from the room singing. "Cinderelly, Cinderelly, night and day it's Cinderelly." Dudley sighed and turned to Sage.

"You want to tell me what all that was about?" He asked.

"Just Zinnia, being Zinnia." Sage said. "Don't worry about it, daddy." She had learned long ago, if she snatched on her sister it just made the picking on her worse.

After watching his daughter for a moment Dudley sighed, and walked over to the bed and lifted up the old box spring and leaned it up by the mattress.

"I'm going to get the hammer to take down the old bed, way don't you clean out from under it while I'm gone." Dudley said. "I'll be back to help you clean out your room in a moment."

Sage nodded then started cleaning out from under the old bed, as her dad left the room, when she found a button. She picked it up and read.

"Support Cedric Diggory." She frown, who was Cedric Diggory. Then right before her eyes it changed to Potter sticks. Startled, Sage dropped the pen. She bent down to pick it up. It most be one of those 3D things that can change when you move it. She tossed it in the trash and went back to cleaning.

She went over to the other corner to start on throwing the books away. She tossed a couple written by some guy name Lockhart, and the ones that was in bad off shape, but she kept some: Quddictch though the ages, Hogwarts a history, a defence against the dark arts book and a potion book.

It was so weird to find something like this in her grandparent's home. People who had yelled at her dad once for letting her watch the Wizard of Oz, and The witches, and about went through the roof when they found out she liked to watch old Bewitched reruns. But Sage always liked things like that. Stories about people with magic and fairies and unicorns. She loved fantasy stories, and she loved to read. Sage hide the books she wanted to keep in a loose floorboard that was under the bed and quickly threw the others away. Then her dad came back in the room with a hammer and bucket of water.

"Here baby girl." He said. "I'll take that old bed apart and you can wash the walls so we can paint." Sage nodded and took the bucket out of her father's hands and he went over and started hammering the bed.

By the end of the day they had cleaned out all the old stuff, and had swiped the floor and mopped it and her dad had taken a hammer and with one hit the old board flew off the window, and they were able to get some fresh air. At one time he had lifted up the cat flip to knock the board off the other side, then stopped and instead took the door down and promised to buy her a new door for her room. Saying he hated this door.

It took so long to do all that, the only thing she was able to bring out of the shed was her bed and some clean clothes. By the time she went to bed that night, Sage was so worn out she fall asleep the moment her head hit the pillow.
