AUTHOR'S NOTE- I have not abandoned One Small Change. I do have major writer's block on it so I'm hoping another project will knock it loose so I can do both. This popped into my head after I recently saw Captain America Winter's Soldier and totally fell in love with Bucky Barnes. This will be AU so totally different from the usual butterfly effect stories I lean towards so there will be differences from both Harry Potter, and MCU story and timelines. Oh yeah and none of them belong to me.

#1- Harry James Potter has been replaced by Juniper Lillian Potter. Personality, background and appearance are much the same only the gender is switched up. Although the personality has been snarked up a bit for the enjoyment of the writer.

#2- In this universe the end of Winter's Soldier, and the midsection of Deathly Hallows coincide both in present day. Throwing out Age of Ultron because I prefer Jarvis to Vision and Friday and Civil war is not happening.

#3- Bucky was 21 when captured by Hydra. I wanted to bring his age more in line with Juniper's I know hes technically around 70 years older but life experience kinda stops when your brainwashed tortured and only pulled out now and then to assassinate someone.

#4- This story will start in Deathly Hallows after the trio is nearly caught by snatchers in the woods causing them to try apparating to Number 12 Grimmauld Place one of the snatcher grab them much like Corbin Yaxley did in cannon much later and they had to abandon it causing Juniper to grab Hermione and Ron and apparate desperately the only thought 'somewhere safe.' Their combined power transport them across the pond to the Avenger's tower in New York.

#5- Thor and Loki are...someplace? I need them out of the way cause I need Voldemort to actually be a concern and even turned up to 11 as I intend to do I think the Asgardian gods could take him out.

#6- Bucky came to Steve's apartment shortly after the end of Winter's soldier and they both moved into the Avenger's tower with the others as if offered more defenses if Hydra tried to reclaim Bucky. (And you know they will.) They are both in residence at this time.

#7- Main pairing is Juniper and Bucky. I am considering Peter(Parker not Pettigrew :).) With either Ron or Hermione but not solid on either any suggestions are welcome.

CHAPTER ONE

When the alarms went off the occupants of the towers where scattered throughout the living spaces. Tony and Bruce in the lab, Steve and Bucky in the gym, Natasha in the kitchen, and Clint in his room napping. At first Tony wasn't overly concerned as Phil Coulson, and Nick Fury often walked through their security despite his updates seemingly to prove they could but as he and Bruce entered the living room Jarvis disabused him of this notion.

"Sir there are intruders in the lower level." Jarvis informed him and if it was possible for a AI to sound puzzled and alarmed he did.

"Its not Agent, or Fury?" Tony asked.

"Could be Hydra." Steve said as he as Bucky entered.

"Lets take a look." The screen flickered on as the others joined them and surprise rippled through them. "If their Hydra someone needs to speak to their recruitment department."

There where three of them. The only guy was a tall broad shouldered young man with long legs and arms giving the impression that he hadn't quite grown into his body yet. He had red hair and freckles wearing trousers and a dark coat. He looked as if he's lost some weight recently and he was pale and dirty the sleeve of his coat ripped arm bloody face scrapped, with a bloody nose and a rapidly blackening eye. He looked to be 18 or 19 tops.

The taller of the girls looked around the same age as the boy she was thin with high cheekbones bushy brown hair pulled back into a ponytail she was wearing a flannel shirt and jeans no coat unlike the other two she had no visible wounds and the blood on her hands seemed to belong to the other two she was holding the boys chin checking his wounds her other hand clutching what seemed to be a simple beaded purse so hard her knuckles where white.

The last of the three looked to be the youngest she was also the only one standing as the other two where sitting on the floor almost huddled behind the receptionist desk her eyes scanning the reception area empty because it was after business hours. She was small boned fragile looking with the same look of not having enough food as the other two. She had long wavy black hair pulled back into a ponytail as well longer than the first girls and was wearing round glasses she was wearing a outfit that matched the other girls. One side of her face was covered in blood as was the shoulder of her shirt. As they watched she removed her cracked glasses pointed a stick she was holding at it and said something they couldn't hear as the sound wasn't on and the glasses seemed to repair before she replaced them.

"Well that was a bit impressive." Bruce said dryly.

"Can we get sound Jarvis?" Tony asked.

"...re we Juniper?" The brunette was asking as the sound cut in.

"I don't know Hermione. The Grimmauld Place safehouse is compromised. we can't apparate into Hogwarts even the room of requirement and we can't compromise the burrow, the Rookery, or Longbottom manor. Trying to teleport to the twins, or Remus would put them in to much danger to risk I just focused on somewhere safe." The smaller girl, Juniper? answered.

"JUNIPER! You could have killed us." She shrieked making not only her companions but the Avengers wince.

"I didn't see you having any better ideas." Juniper snapped then glanced at the boy. "Ron you okay?"

"Shaking it off." The young man answered shaking his head. "Hit me from behind bloody wanker." And like the girls they could hear the English accent in his words.

"Yes well Snatchers, and Deatheaters don't tend to play fair." Hermione said sounding a bit distracted as she turned her attention to her bag and reaching much farther into it than should have been possible and pulled out a vial handing it to the boy, Ron. "Pain potion." She held out a matching one to the other girl as the boy took it and swallowed it down. "Juni?"

Juniper shook her head. "Save it we may need it more later no telling when we'll be able to get more." A look of guilt flashed over Ron's face and he seemed to take a good look at the smaller girl for the first time.

"Merlin Juniper how hard did you hit that tree." He asked eyes on her shoulder.

She shook her head distractedly. "That blasting curse clipped me a bit thats all."

Hermione looked up at her as well. "Juniper oh no sit down before you fall. How much blood have you lost?"

"I'm fine Hermione." She answered. "We need to figure out where we are. We have to get out of here. This is a urban area if they find us here they'll be massive muggle casualties its not like the Deatheaters care about the statute of secrecy."

"The suns already down." Hermione said softly. Her eyes found the big clock on the wall. "It says its after seven. That puts us in...the American East coast. Merlin Juniper did you apparate us across the ocean."

"Would explain the exhaustion." Juniper answered.

"So would the not sleeping or eating we've been doing for the last few months." Ron said dryly. "We should stay at least long enough to get a solid eight hours and a meal."

"Honestly Ron must you always think with your stomach?" Hermione asked.

"When its this empty yes Hermione. You know I know how important it is we get back. Don't forget your parents may be safe in Australia but mine are still back in Devon, Ginnys at Hogwarts, Bills at Gringotts and the twins are on Diagon Alley. Only Charlie is safe in Romania." Ron answered his tone a bit testy.

"Who are these kids?" Clint asked frowning deeply speaking the words they where all thinking. The conversation had unsettled all of them as far as they where aware there where no conflicts currently being waged in England but the three spoke as if they where in the middle of a war. And it wasn't only their words or even the wounds and hungry dirty appearance as if they'd been living hard it was the way the two older ones crouched as if using the desk as cover. The way the younger looking girl's eyes constantly scanned. Even the way they spoke to each other a bit to sharp and impatient to be polite as if they where so closely bonded that they didn't have to watch their words or tone because no matter what happened they would never turn on each other more like siblings than friends.

"Soldiers. Warriors." Bucky's voice was hard as his gaze locked on the screen. He recognized their movements and stances the wariness and hardness of their eyes. "I know I've been in stasis for a while but I didn't realize the Brits where at war with anyone."

"Neither did I and as Earth's mightiest heroes we should know this stuff." Tony said. "I think we should have a little conversation with our guests. Jarvis bring the lights downstairs up on dim and turn on the intercom."

As the lights came up slowly it took a moment for the trio to realize it but the second they did they moved like lightning with no discussion seemingly completely on instinct back to back sticks like the one the girl was used to repair her glasses in their hands.

"Nice moves your fast." Tony said into the intercom his voice echong slightly. "Welcome to Avenger's tower. This is Tony Stark. I'm assuming you came here for help." He said as if he'd not heard any of the explanation the girl had given on how they had ended up where they had.

"No No we're sorry we didn't mean to trespass but we need to go now." Juniper said and grabbed each of the others arms and her eyes fluttered for a moment then swore.

"Juni?" Hermione hissed.

"I don't have enough juice left. Can one of you apparate us?" Juniper answered

"We can't get us across the ocean and we don't have any point of familiarity around here. We aren't as strong as you Juniper." Hermione answered.

"You can come up sit down have a meal and recover a bit have a breather then we'll see about getting you back to where you need to be." Steve said his voice reassuring.

The three turned so that they where facing each other and seemed to have a whole conversation without words. "Jarvis open the elevator for them." Tony said softly. The boy jumped slightly as the elevator door slid open.

Hermione and Ron both looked to Juniper making it clear who the leader was if it hadn't already been obvious.

She looked at the other two seeing their pain, exhaustion, and hunger. "Okay." She whispered softly then nodded. "Okay that sounds...okay." She led the way onto the elevator and Jarvis switched seamlessly to the elevator cameras and speakers.

"They saw us use magic." Ron said softly.

"We can't worry about that right now. Its too late anyway. We react for the situation not as it should be or we wish it was but what it is. They saw things they shouldn't have so we just have to ask them to keep quite about it." Juniper answered leaning against the elevator wall but straightened to stand with her two companions as the elevator came to a stop and the doors slid open.
