Found
Thirteen years after the Scamander had lost their daughter, the Potters were on a summer break in Spain. Two of their children were at Hogwarts school of witchcraft and wizardry. The eldest, was called James Sirius Potter and was about to enter his fifth year. He was a proud Gryffindor and was a troublemaker, just like his grandfather. The second son was called Albus Severus Potter. He was entering his third year at Hogwarts. He was the only Slytherin in the family and normally kept to himself. His best friends were Scorpius Malfoy and Rose Granger-Weasley. The Potters had a daughter called Lily (like Harry's mum) Luna (Ginny's best friend) Potter. She was entering her first year at Hogwarts.
The three kids and their parents, Harry and Ginny, were having a relaxing day at the pool when Harry had a call from his best friend and minister of magic, Hermione Granger.
She told him, " the Auror Bolt has found a source of magic in a completely muggle neighbourhood. I know that you are on a vacation but since you're in Spain, could you go and check it out?" At this point, all the splashing had stopped to listen to Harry.
"Yeah, of course, I'll go right away," Harry replied in a serious tone.
"Thanks. Goodbye Harry." the voice said.
"Bye 'Mione." he put the phone down and was met with his children’s pouty faces. He was asked millions of questions like Where are you going? Can we come? Is it a secret mission? and so on.
"Kids, kids. One at a time," Ginny laughed, "his ears are going to pop"
"Where are you going?" Albus asked Harry.
"I'm going to a muggle neighbourhood. Bolt has found a source of magic there and since I'm here in Spain, I'm the one who's closest." his face was saddened.
"So, can I come?" James asked eagerly. He's been wanting to come to one of Harry's missions since he learned what he wanted to be when he was older.
"No James. You can't." Harry said. Merlin had he been asked that question.
"I don't see why not," to Harry's surprise, Ginny said that, "Well, he is fifteen and he does want to be an Auror so, you can show him the basis. You're not going on a secret mission because otherwise you wouldn't have told the kids." This struck Harry like the lighting bolt he had on his forehead.
"Well, okay. But just this once. And only James." he said when he saw the other two faces lit up.
Not so far away, a girl called Charlotte was humming to herself returning from a walk down the hill next to her house. When she arrived, she went up the stairs to her room and licked herself in it. She looked at the drawing on the wall she was painting. Taking her paintbrush and wetting it in paint, she began stroking the
wall with it gently. The drawing was a white hare with a misty trail behind it. A popping sound startled her. She looked behind her and saw a man in his mid-thirties. He had messy black hair and green eyes, a faint lighting scar was across his forehead right above his right eye. Next to him, was standing a replica of him but younger, about two years older than her. He had blue eyes and messy black hair.
"Can I help you?" Curious about why and how they were in her room.
"Are you Charlotte?" she nodded, "We need to talk to you"
"Who are you?" Charlotte said. Could she trust them?
"My name is Harry Potter, and this is my son James." Harry said, "I am an Auror, like a muggle police. A muggle is someone who doesn't have magic. We are wizards and you are a witch."
She stared at him with an open mouth. It's not possible. Her life was as normal as can be. Well, with exceptions. "How do you know? Are you sure? Is this a joke 'cause I'll be very disappointed if it is" Harry smiled at her words. But not the cheeky smile or the smirk smile but the kind smile.
"Magic,yes and no," James said behind Harry. Charlotte sent him a confused look and so did Harry," We know by magic, yes we are sure and no it isn't a joke." he explained.
Charlotte sat down on the bed, Harry knelt at her side and looked her in the eyes," We are only offering you to come with us to England so you can learn to control your magic."
The girl looked up and asked, " Where will I live? It's not likely that my parents are going to let me stay after I tell them or run away."
" You can live with us. But if it's any comfort to you, they aren't really your parents. Just adopted." Harry said. Charlotte's face lit up. She was so happy that
they weren't her real parents. Now the only question bothering her was How she was going to tell her 'parents' .
"Okay. But first I need to pack" Harry reached in his pocket and took out a small suitcase
"Here, it has an expandable charm on it. James help her pack, I'll go and erase your adoptive parent memories so they don't go and search for you" he left.
She opened the suitcase and laid it on the bed. Reaching for the closet door, She told James to start packing the drawers on my bed night table. He did as he was told so She started with the clothes. After twenty minutes of packing, Harry came back and told them that she was a great part of their memories and at least the memory of her aspect will stay. She looked at her now empty room and smiled. She was finally leaving this house.
"Okay, we will apparate to the house we have here and in a week we will leave for England to get you installed." Harry took the suitcase and told her to take hold of his arm. James held onto his father's arm so she copied him. Harry apparated them outside the house. Ginny came rushing with Albus and Lily behind her.
"How was it? All good?" Ginny asked. She caught sight of Charlotte and gasped. It couldn't be. The girl reminded her of her best friend Luna Lovegood. Her messy platinum blond hair and her misty blue eyes. She was a replica of her. She whispered to Harry, " She looks just like Luna when we were in third year. You don't think she's her missing daughter?"
Harry's eyes widened. Of course! How could he not have seen it before! Platinum-blond hair, misty blue eyes, kind smile, the drawings on the wall. She was definitely Charlotte Ginnervay Scamander. The six of them entered the house into the living room. " Albus, Lily, this is Charlotte. She is a witch and just discovered it. Albus,she's in your year, be her friend. Lily, don't drive her nuts and James, be nice and no pranks." Harry said, " Show her the guest room and make her feel welcomed. Then go to the pool if you like."
The kids went up the stairs to show Charlotte her room. Ginny sat next to Harry on the couch and sighed. " What are we going to do?"
