~O0o-Harry Potter: Prisoners and Walkers-o0O~

~O0o-First Book of the Walker Chronicles-o0O~

Pairing: Harry/Katie (For now may add two more girls later on.)

Summary: Multiple crossover. It's shocking how one little chance of fate could alter the way things go for Harry Potter. Set in third year.

This is an AU of the Harry Potter world according to my imagination so it's safe to say that where all fucked beyond belief don't you think? I got the idea for this fic after reading Alistor's fanfic: Harry and Susan and the Prisoner of Azkaban. A Harry/Susan pairing. I liked the idea, but wanted to choose a different girl so Katie was chosen. The other girls will be introduced later on, not sure on when yet.

On with the show! Enjoy!

Chapter 1: Meeting Your Mate.

~O0o-Dec. 18, 1993-o0O~

'Well this bloody well sucks,' thought a groaning Harry Potter as he sat atop the Astronomy Tower watching as the carriages left for the train station. He was dressed in casual muggle attire: dark grey, long-sleeve shirt, dark blue jeans, and his old trainers. The reason for Harry's rather sour mood was simple; he was going to be alone at the castle for the winter holidays. This wasn't the original plan of course since his two best friends, Ron Weasley and Hermione Granger, were going to stay in the castle with him. Those plans, however, were shot to hell a few days before break.

It started with Hermione getting a message from her parents that she needed to come home for the holidays since her uncle, Adam Granger, was coming for a visit, and she and her family hadn't seen him in years. She was uncertain at first, but Harry and Ron encouraged her to go. After much back and forth between them, she finally agreed to go. Ron and Harry hadn't worried too much since they were both going to be there…or so they thought. The next day Ron got an emergency call up to the headmaster's office. Harry found him later that evening packing his stuff along with his brothers. Apparently, his brother Charlie had a run in with a dragon on the reserve in Romania and was injured; so Ron and the family were leaving to see him.

Harry sighed, 'Now it's just me and the staff here for the hols. Oh the Joy!' He was shocked when he realized that every other student had also gone home except for him. Leaning against the railing, he glared out over the school towards the train in Hogsmeade. He suddenly caught movement and his eyes shifted instinctively to the source. Three years of being a seeker had sharpened his ability to find movement to the point where it was almost instantaneous. He noticed someone walking toward the Black Lake with shoulder-length, dark brown hair wearing a dark green hoodie and jeans. Harry at first thought it was a Slytherin, because of the green, but wasn't sure and decided to check the map in his back pocket.

"I solemnly swear that I am up to no good." Harry whispered as he pointed his wand at the map. Once the enchanted maps ink had finished its spider web-like movements, Harry glanced over it trying to find who the person he saw was. He noted the professors in several different locations as he attempted to find the location he was searching for. When he finally locked on to the name he felt a grin cross his face.

Katie Bell

Harry met Katie in his first year when he joined the Gryffindor quidditch team, and immediately grew to respect and like the young chaser. Those feelings grew to a crush for her that he had in his second year when she approached him, after the rumors started about the chamber, to tell him that she believed him when he denied being the Heir to Slytherin. When he saw her this year, he realized that his feelings grew stronger over the summer and that he could honestly say he fancied her. He resolved to try and get to know her better outside of quidditch this year, but outside sources seemed to be stifling that idea.

'Now's my chance,' he thought with a grin; stowed the map and made his way out of the castle, pulling on his dark blue hoodie.

~O0o—o0O~

Katie sat down on a large root under a tree near the Black Lake with a sigh. 'I can't believe it didn't work.' Katie thought with a huff. She owled her family the other day when she heard that Hermione and Ron would be going away for the hols and Harry would be staying at the castle alone. She'd been hoping to have a chance to talk with him this year to get to know the young teen better. She knew that she was falling for the young seeker hard, but never approached him for fear of scaring him off. She was a very perceptive person and could read Harry very well; she could easily see someone who wasn't very sure of and kept to himself so she wanted to give him time before she openly pursued him. 'All that planning and he's not here.'

"Why the long face sunshine?" came a familiar voice.

She turned and let a happy grin cross her face at the nickname he'd given her last year. The boy she had just about given up on finding finally appears. What was it her dad told her once, 'ask and it shall appear?'

"Harry? What are you doing here? I figured ya'd be gone for the holidays." Katie said fanning ignorance.

"Nah. I'm stuck here, but I thought I'd be the only one. Didn't know I'd have to share with the prettiest girl in Gryffindor," he said cheekily; grinning as he saw a soft blush coming to her features.

'Does he really think that?' she thought with hope. 'Maybe I do have a chance.'

"When did you become so suave Harry Potter?" she asked with a giggle.

Harry sported his own blush at her musical laughter, but was cut off from answering by a low grumbling sound. Both teens looked down at their respective bellies that were giving complaints at being forgotten and both started laughing heartily at their situation.

"Care to join me for lunch fair lady," asked Harry holding out his arm for her. 'Hope I'm not being to forward.'

"I do declare, fine sir. I think I shall," answered Katie taking his offered arm and leaning into his side. 'Perfect.'

~O0o—o0O~

The two teens walked arm in arm into the Great Hall, and stopped in awe of the sight before them. The hall had been decorated for Christmas and looked beautiful: conjured snow falling, 40ft. Christmas tree in the corner, and wreathes hanging on Christmas theme lanterns. Harry and Katie both grinned when they looked at all the decorations.

'Nothing beats Hogwarts at Christmas,' they both thought.

Looking down the table they were surprised to see Professors Dumbledore and McGonagall playing a game of wizard's chess on the one lone table in the hall.

"Evening Professor McGonagall. Headmaster," greeted the teens as they approached the teachers. Harry noticed a small shock of white hair next to the headmaster that he didn't see at first. "And you too Professor Flitwick."

"Good evening Mr. Potter. Ms. Bell. Here to grab some lunch I take it," said Dumbledore as he munched on one of his sweets; waiting for McGonagall to make her move. "Nimble?" a small house elf appeared with a soft pop. "Would you bring some lunch for these two?" he said pointing at the two teens. After getting their order, the elf disappeared with another pop.

The two teens settle next to the three professors and chatted happily before their food arrived.

"Are you two looking forward to Christmas as much as I am? I'm sure this year I'm bound to get a wonderful pair of socks," said the headmaster with a grandfatherly smile. This drew snorts and chuckles from the other two professors and Harry, but a confused look from Katie.

"I'll tell you later," whispered Harry to which she nodded.

"And what are your wishes for Christmas?" McGonagall asked the two teens after finishing her move.

"I'm not sure, my plans got changed in a hurry and to be honest I'm just glad Harry is here to keep me company," said Katie with a playful bump to Harry's shoulder.

"Don't know. I've never really been one to ask for something for myself, but I'd really like for someone to sign my permission slip so I could go to Hogsmeade." Harry stated with a sigh. "I've heard it's great."

McGonagall looked sadly at her young lion. She'd truly wanted to sign his slip for him when he'd approached her about it earlier in the year, but she wasn't his guardian and as a professor she couldn't show favoritism. 'Unlike that man!' she thought with distaste.

Dumbledore, however, was stroking his beard thoughtfully; he gave a smile at the boy. "Well Harry. I'm going to be going into the village today to take care of a few things. I wouldn't have a problem if you would like to join me," he said; smiling when he saw that happiness on Harry's face.

"That would be great professor! Would it be ok if Katie came with us?" asked Harry in excitement missing the happy blush on Katie's face.

"Of course Ms. Bell can join you my boy," Dumbledore replied his eyes twinkling playfully.

~O0o—o0O~

"I'm surprised," stated Harry as he and Katie followed the headmaster to Hogsmeade.

"About what Harry?" asked Katie.

"I honestly thought we'd be set on by Dementors as soon as we left the grounds," replied Harry. "They seem to have an unhealthy fixation with me." Ever since his first quidditch match his fear of the dark creatures had only increased. Luckily, he'd convinced Professor Lupin to teach him how to fight them, but he'd have to wait till after the holidays.

Katie's heart went out to the black-haired teen; she remembered that day at the quidditch match when he was attacked by the dark creatures. Her heart stopped when she saw him falling and was extremely grateful to the headmaster for saving Harry. She took his hand and gave him a reassuring smile which he returned.

"Tell me about your family," said Harry trying to steer the conversation toward something more positive.

"Well I have my mom and dad, my older brother, and little sister." Katie said with a smile. "Jason and Elaine Bell. They both…um…hold special jobs within the ministry. Sorry, I can't say more about it than that. My dad was born in the states, but was sent over here to provide aid during the war with Voldemort and chose to stay after meeting my mom since she was one of the ambassadors who went over for aid." Harry stopped to give her an odd look. "What?"

"You actually said his name. Well his fake name anyway," said Harry with respect in his voice.

"Thanks," she mumbled with a blush. "What do you mean fake name?"

"Lord Voldemort is part of an anagram he made up from his real name. Tom Marvolo Riddle," explained Harry. "Tom Marvolo Riddle makes I am Lord Voldemort if you move the letters around. He was a student at Hogwarts many years ago."

Katie looked at Harry with shock and awe. She had never heard that. "Wow. That's something else." 'I'll have to tell mom and dad about that.' "Any way my mom and dad taught me to never fear the name, it only makes you more fearful of the creature."

'I'm going to enjoy meeting her parents. They sound great,' thought Harry.

"My brother was a seventh year in Hufflepuff your first year. You might remember him as one of their chasers. Edward Bell, but everyone called him Ed." Harry nodded. "He's now a reserve for the Kenmore Kestrels. He sent me this hoodie last year for Christmas after he was selected in the draft. And my little sister is nine, her name is Annabelle, but we call her Anna."

"You sound like you have a great family Katie," said Harry with a sad smile wishing for a family like that.

Katie noted his smile, and reached for his hand and gave it a squeeze.

~O0o—o0O~

Upon arriving at the village, the two teens split from the headmaster and made their way around the town. Noticing that there were a lot of people running around for some last minute Christmas shopping.

"Where to first?" asked Katie.

"Is there a Gringotts branch here? I got to get some gold first," asked Harry. He was answered with a nod from the pretty chaser. It didn't take long to reach the branch and get what he needed.

"Have you gotten all your Christmas shopping done?" asked Harry.

"Not all of it. Still got a few last minute things," replied Katie.

"Alright, how about this? We split up to get what we need done since I have a few things to get too. Then we can meet up at the Three Broomsticks for an early dinner," he finished with a wink.

"Sounds like a plan," Katie replied with a blush thinking it sounded remarkably like a date.

~O0o—o0O~

Harry's first stop was Hogsmeade's branch of Flourish and Blotts books to grab Hermione and Professor Lupin's gifts, as well as pick up a few books for himself that caught his eye. His next stop took him to World of Quidditch, Hogsmeade's local quidditch shop, to get some new gear for his teammates that he decided to get customized; he also managed to find something for Ron while there. This was followed by Gladrags Wizardwear for Dumbledore. He also managed to work in one final stop, before making his way toward the post office to send off most of his gifts to his friends. This left only his gifts for the professors, Katie, and Hermione's gift which he planned to send with Hedwig in a few days since she was still in England. With his business done he made his way to the Three Broomsticks.

He entered the pub and noticed that it was surprisingly quiet compared to the rest of the village. He saw Dumbledore talking with a cloaked figure that he couldn't see, but quickly put it out of his mind when he spotted Katie sitting at a booth. Harry noted as he made his way over that she'd taken off her Kestrels' hoodie and was clad in a loose, blue blouse that showed off a bit of cleavage that made him blush slightly for noticing it.

"How'd the shopping go?" she asked as he sat down. She was curious why she didn't see more bags.

"Good got everything I needed to and sent it all off by post. Except for the professors, your gift, and Hermione's gift which Hedwig will take. How about yours?" asked Harry.

"Got all mine done too," she replied.

Madam Rosmerta, the curvaceous owner of the tavern, made her way over and asked if they would like anything. They both placed their orders and were brought some warm butterbeer. The two teens talked on and off over their dinner about all manner of things: quidditch, friends, school, and to a certain extent their families although Harry never said too much about his. It was getting dark when Dumbledore said it was time to go. They bid a good night to Rosmerta and made their way back to the castle.

~O0o-Dec. 24, 1993-o0O~

Katie's eyes fluttered open as she awoke on Christmas Eve. It had been a great week for her since the holidays started. She got to know her seeker as more than just a teammate and was slowly falling deeper for the young teen. She was patient; not pushing him too far or too fast, but still showing that she enjoyed her time with him.

Throwing the covers back, she stood and stretched her toned, athletic body as she walked over to a full length mirror. She had her dark brown hair hanging in her eyes and down to her shoulders, slightly messy; her skin a nice light, tanned color with the only scrap of clothing being a red, lace thong. She could easily be seen as a gymnast or Olympic swimmer with her body. 'I've always been tall for a girl (5'5") and always thought my best features were my legs and ass,' she thought with a grin as she turned to look at her rear; giving it a little shake. 'Although,' she cupped her perky B-cup breasts, 'I wish I could be a little bigger up top. Harry seems to like me just fine though,' a giggle started from her lips.She was happy when she noticed Harry checking out her assets one day while they were flying at the pitch together, and boosted her feminine pride quite a bit. She grabbed some workout clothes to change into and made her way to the shower.

~O0o—o0O~

While Katie was admiring herself, Harry was leaving the land of dreams himself. He yawned sending a grin at his canopy. He'd had the best week of his life and it was easily due to the company of his sexy teammate. He jumped out of bed with an extra spring in his step that was also due to her. The day after their trip to Hogsmeade, Katie and Harry talked about his skinniness, height, and his eyes. Harry was shocked that his physical problems could be fixed by simply seeing Madam Pomfrey; so he made the trek up to the hospital wing that day. Poppy provided him with a nutrient and growth potion to help with the years of neglect from the Dursleys; along with a vial of eye-drops that would fix his eyes. She said she would have given them to him earlier, but he'd never asked which frustrated Harry to no end; she also warned him however that while the potions would help he would still need to make changes to his diet and exercise. Thus began his daily workouts with Katie.

After taking his drops for his eyes, he made his way into the loo and looked at himself in the mirror. The potions, exercise, and better eating had turned him from short, skinny thirteen year old into a 5'6', 115lbs athletic, toned thirteen year old. Like Katie, he could pass for a gymnast or swimmer and looked great for his age. He grinned thinking of the time he'd caught Katie drooling at him the other day. Upon finishing his shower, he dressed in a tight black t-shirt, red workout shorts, and white-black sneakers. He was glad that during the summer he'd gone against the Minister's request to stay in the alley while he was stuck at the Leaky Cauldron and gotten some real clothes for himself.

With one final yawn, he left his dorm making his way down to the common room. The sight that greeted him made him stopped in his tracks. Katie had chosen to wear her black workout pants that were tight around the hips and rear, but flared at the bottom with a red sports bra. While this would be amazing to see to begin with, what stopped Harry was the fact that she was currently bent over with her legs spread as she was performing a side split showing off her flexibility. He couldn't tear his gaze away from her form. Her toned body showing her soft, but firm muscles as she went through her stretches; 'and don't even get me started on how great her ass looks.'

"Enjoying the view Harry?" said Katie as she looked over her shoulder with a sly grin when she switched to a forward split.

This brought a blush to his face for being caught. He gave a shy nod as he took his place across from her and went through his own light stretching. He may be slowly becoming more confident thanks to Katie, but it was still hard to break nearly thirteen years of habits that kept him alive. His confession only made her smile more with a light pink tinge to her cheeks. After a few short stretches, the two teens made their way out to the grounds for a short run.

Katie took it upon herself after Harry's trip to the hospital wing to help him exercise and get in shape. Harry didn't mind since it allowed him to spend time with the girl he was crushing on; likewise Katie didn't mind since it allowed her time with Harry, while also molding him to her liking a little physically. She had to admit she was doing a good job too.

Their workout progressed each day since they started. They now were making a few laps around the castle grounds since Harry was a good runner to begin with, but the change in his body made him heavier than he was used to and needed to work on feeling natural while doing it. Their run was followed by returning to the common room and going through a more thorough stretching routine since their muscles were warmed up. Katie then brought out a few weights that she brought to school for her own use: Kettlebells and Clubbells. They would alternate each day with using the weights and doing bodyweight exercises: push-ups, sit-ups, pull-ups, handstands, Kong and ape walk, bear-crawls. They would offset their routine from time to time with flying practice so he could get used to his body in the air, unfortunately he had to use the school brooms still since he'd yet to get a new one. The first day Harry was dying and was close to cursing Katie…if he could raise his wand much to her amusement. However, he got better each day thanks to the potions, and was now thanking her for working with him, plus being able to see her in her workout clothes and sweaty was a great reward too.

Their workout ended with them both collapsed and panting on the sofa in the common room with a bottle of water each. Both made small talk and did some light flirting with each other which they'd become accustomed to over the last week. After they'd cooled down they both made their way up to their respective dorms to shower and dress before heading down for lunch.

~O0o—o0O~

Later that evening found both teens on the sofa in the common room reading as they lounged next to the fire; each had a blanket close by. Katie was in a loose, silk pajama set of black and red that hugged her body nicely; reading a new Inside Quidditch magazine that arrived by owl earlier. Harry wore a grey, sleeveless top and black sweatpants; reading one of the books he'd acquired during their Hogsmeade trip, The Beginners Guide: Runes & Warding. Since the start of the semester, Harry grew to detest Divination and regretted not dropping it immediately. Unfortunately, the same could be said for his Care of Magical Creatures class, although it wasn't to do with the teacher just the subject.

"Something wrong Harry?" asked Katie when she heard him sigh.

"Just annoyed that I didn't take more time to review the classes for our electives. I would have taken Ancient Runes and Arithmancy instead of such a useless class like Divination. I may not of taken Care either; I like Hagrid and all, but he lost all his confidence after that incident with Malfoy and Buckbeak," replied Harry.

"I know what you mean," said Katie with a nod. "Alicia and Wood both warned me about Divination since they took it their third years. That's why I chose Runes and Arithmancy." She giggled at the surprised look on Harry's face. "What? I'm not just a pretty face and great ass ya' know? They interested me and I wanted to take them. Plus Ed told me I should take them."

Harry laughed at her joke. "Anything I could do to get out of those classes?" he asked.

Katie took on a thoughtful pose; laying her magazine on her lap. "I'd say ask Professor McGonagall first and see what she has to say about the idea. If nothin' else ya' might be able to switch for next year," she said.

Harry nodded and went back to his reading. After a time he looked over at the Christmas tree that was in their common room and noticed how empty it looked. "Got anything you're really hoping to get for Christmas?"

"I'm hoping to get a new broom since mine has gotten pretty beaten up over the last few years, but I won't complain if I don't get it. It's not about what you get, but about what you give," she said happily. "How about you Harry?"

By now both teens had put their respective reading material aside. "Like I said the other day, I've never been one for asking for presents." Harry stated with a sigh.

"How come?" she asked.

Seeing the honest curiosity in her eyes he decided to answer a question that he normally would rather no one knew, but he knew that he liked her and wanted her to know as much as he was comfortable letting her know. "Well, I live with my aunt, uncle and cousin; have ever sense my parents died. In a normal family this wouldn't be too bad, but unfortunately for me my relatives don't just hate magic, they despise it. To make matters worse, my aunt hated my mother too. My childhood, if you could call it that, consisted of countless chores and damn near waiting on my family hand and foot. Hell I didn't even know my name till I went to primary school, they just called me Freak. Any time I did anything that they thought was abnormal or bad I was punished. Burn the bacon: Punishment. Don't dry the clothes enough: punishment. Do better than Dudley in school: Punishment. Breathe wrong: Punishment. I never got anything for Christmas or my birthday, and if I ever asked they just told me that I wasn't worth asking for anything."

Katie could barely hold back her tears as she looked at the young teen that'd been making a home in her heart for the last few years. How could anyone who was supposed to be family treat a child like that. Like many she'd heard the rumors surrounding Harry since his first year, but honestly never really believed most of it since he never told her about it. Her parents taught her right after all: never believe anything that doesn't come from the source. She saw Harry bowing his head, and realized how hard it must have been to tell someone all of that, she felt like she'd been told a drummed down version too.

Harry felt drained and embarrassed after he finished his story to Katie. He bowed his head not wanting to see the pity, or worse rejection, he might see in her eyes. So he was shocked when he felt gentle arms wrap him in a hug. He stiffened at the contact, but relaxed and returned the embrace.

"It's going to be okay Harry. I don't think any less of you and I'm honored that you would trust me with that," she whispered in his ear and kissed his cheek.

"Thank you Sunshine," whispered Harry as he looked into her tearful eyes. He leaned forward and kissed her cheek in thanks; they both smiled at each other. They both sat back and relaxed on the sofa with Harry's arm around her shoulders and her head on his shoulder. Both talked more into the night until they both fell asleep.

The house elves appeared in soft pops and put presents under the tree while the teens slept and disappeared just as quickly and soundlessly as they appeared. After the elves left, the portrait opened and a tall dark figure walked in holding a long, wrapped package. He was a pale, sickly man with long, scraggily black hair and an un-kept beard. He wore a striped prisoner outfit that barely fit his thin frame. He placed the item at the base of the Christmas tree before he noticed that the fire was still going. He thought that curious, believing someone to have forgotten it, and went over to put it out before sneaking out. It was then he saw the two teens cuddled together on the sofa and gave a sad smile.

'I'm happy for ya pup. Maybe after this business is done we'll be able to be a family as we always should've been,' he thought.

He left quickly so as not to wake them. Neither would know that Sirius Black, supposed mass murderer and follower of You-Know-Who, had visited them on Christmas Eve.

~O0o-To Be Continued-o0O~

And so ends the first chapter of this fic, hope you enjoyed it. I'm currently working on my other fanfic: Harry Potter and the Wolves of the Nevernever, and will be alternating chapters for a while.
