My first fanfiction in english so I'm sorry for any mistakes. A warning: In this fanfic, the firstborn of a magical family (purebred or half-blood) has a greater control over the magic of the family, that is, the magic in the house and that is in the blood of the family. This skill is technically important only when the current head of the family dies, for then the firstborn becomes the one who best controls the magic, if the firstborn is female, the greater control ends when the first male heir marries, since he becomes the head of the family and gains more control over the magic.

Full summary: Marie Bosse needs to get away from France. The Dark Lord is becoming more influential in the french magical community, and even if it breaks her heart she can't stay in her homeland, not when his followers wait for her family's support. So the girl has to go to a place that, according to her parents, is the most secure in the world, Hogwarts. Marie didn't expect her time at Hogwarts to be good, her parents didn't give her a lot of information about the school and all the stories she had heard about the place weren't informative, add to that the fact that Harry Potter is in her year, something that to her shows that safe is the last thing she will be, but she didn't expected that she could be surprise and that her opinion about the school (and it's students) could change so much.

The sound of birds and the gentle rays of sun woke her up earlier than she had planned. The light shining through the window hit her closed eyes, her eyelids covering most of the clarity while making the world a scarlet ocean, different shades of red popped up in sight, her sleepy mind trying to understand why suddenly the blackness had given space to another color.

Unwillingly, she opened her eyes and looked at the culprit of this disturbance, her light blue curtains were open, probably the work of one of the house-elves, the morning sun happily shining during the most likely beautiful summer day didn't have any problem to flood the room in a spectacle of multicolored lights forming a giant rainbow over her room.

It was a marvelous view, the light wooden Alder closet doors, vanity and chair now seemed to be made of various colors. The walls, covered in pearly wallpaper with golden accents were a copy of Bifrost, giving the room a fantasy feel.

Even so, she didn't want to wake up, not yet. She had spent almost 7 days awake, too stressed to rest, and too tired to really do anything productive, drinking Wideye potions to stay awake, her mind in an endless loop, repeating what her parents had told her the moment she stepped into their home after coming back from school, trying to understand the meaning of it and link it to all the strange letters through the school year, the we-are-so-perfect smiles that now seemed obviously fake to everyone, the glares over the shoulders on the way out of the picking-up point and the hurried route to get to safety, get home, with much more wards and runes guarding it than she could ever remember.

After 7 days, 14 potions and almost falling off one of the many stairs at home, she had finally been too tired to stay that way and the elves, not wanting to be punished for anything that might happen to her in her sleepless state, were more than happy to get a dreamless potion from the potions cabinet. That was why, even though the view was breathtaking and the smells that lingered on the place were a mixture of fresh baguettes, croissants, Iris and all the other flowers on the garden, her favorites, she didn't have the energy to move.

A loud pop made her heart jump and then beat like crazy, her eyes, that were starting to close opened fast, her right hand instinctively found her wand on the magical holster in her biceps, where it had been in all moments excluding when she was showering since she arrived home. She moved to a sitting position as fast as she could, the years of dueling lessons making her movements automatic while her eyes and brain looked for the source of the sound and the possible danger. Standing maybe 10 feet away from her canopy bed was Mabrey, the elf was visibly startled, looking at her with bright big brown eyes and clenching his hands. She let go of the breath she didn't notice she was holding and put the wand back on the holster, waiting for an explanation as to why he had come.

- Mabrey came to give a message to Mademoiselle Bosse. Monsieur Bosse and Madame Bosse await for you in the first dining room in ten minutes, they will not tolerate tardiness and expect you to be well dressed for this gathering. - The elf said all the words slowly, careful to enunciate every one right and clear, his eyes looking anywhere but hers, lowered to the level of her chin.

Even with all the "correct way of speaking" her mother had forced all the house-elves to have and all the punishments for any wrong wording or conjugation they couldn't speak as fast as wizards and Marie was sure they never would, not when their mother language was not the same as their masters.

- Tell mother that I will be there in time Mabrey. - She wanted to be nicer to the elves, but when she last tried they were utterly astonished and begged her to not talk like that to them, too afraid of her mother and what she could do to them if her daughter acted as if they were worth her time.

The elf bowed his head and vanished with another pop. Marie got out of bed, throwing at it the blankets she used knowing that by the time she came out of the shower they would be perfectly placed as always.

She went to her window, opening it so the perfumed air could get inside, the view of the garden with its beautiful flowers cheered her a little, giving her some energy to get through the morning. Her bathroom door was right beside her vanity, when it was opened she was greeted by her reflection that showed dark circles under her eyes, her fair skin had more of a gray color after many restless nights. She took off her clothes and left them folded on the ground, the holster placed on top, going straight to the shower. The cold tiles on her bare feet sent shivers up her body and when she finally turned on the water she was feeling chilled. The hot water made steam rose up all around her, she finished fast not wanting to waste time washing her long hair. The fluffy tower was wrapped around her figure, and she exited the room.

Her next stop was her closet, it was fairly big, one of those walk in closets, full of dividers for her many clothes and accessories. She went over to her muggle dresses, even though her mother preferred dress robes, she was not against muggle clothing, especially if they were figure flattering. She chose a gray one, below her knees and embroidered on brown, paired with light pink shoes. Her jewelry consisted of a golden necklace with a small sapphire fox and her earrings were sapphires in teardrop shape, her jade ring was an heirloom, giving her the title of heir of an old wizard family. She did a quick makeup and let her hair fall naturally to its slight curls.

Getting the holster with her wand from the bathroom and fastening it around her biceps again where it became invisible as always, she opened the door and made her way to the dining room. The corridors were bright due to the glass windows and the aquamarine walls were adorned with paintings from landscapes to portraits of generations upon generations of Bosse. She greeted them by name, hours and hours studying her genealogy paid off, she knew their history by heart, as well as the history of other wizard families. After going down two sets of stairs she walked through another corridor until she came upon a set of mahogany doors and before she could touch them, they were opened from inside.

A large table stood in front of her, made from the same wood of the doors, the walls on this room didn't have any frames nor windows, it was lit by silver candle holders. At the head chair her father was sited, he was dressed in black dress robes, holding Le monde sorcier, his breakfast untouched. Her mother was at his right side, her blue dress robes standing out in comparison with her husband's, she held a book about politics, one of the many in the house. Her hair and makeup were perfect as always and her untouched plate held only some fruits.

Moving her eyes to her father's left side she smiled a little, her twin brother seemed as cheerful as always, his smile was bright and unlike her parents he looked relaxed, his light orange dress shirt and dark jeans a contrast with his fair skin. She went to the chair on his side, the elves in the room closed the door and pulled the chair for her. Sitting quietly she started to choose her breakfast, a whispered good morning to her brother and his response were the only sounds in the room for some moments.

Her mother put down her book, giving it to one of the elves to put away, she then looked at her children, her piercing blue eyes were as hard as steel and Marie felt as if she could see everything that the girl was thinking even if she was not a legilimens.

- Marie, have you finally stopped the foolishness of drinking those potions to stay awake? - Her mother asked after looking at her for a long silent minute.

- Yes mother, I am sorry for worrying you. - Marie's reply was all but practiced after years being on the end of her mother's reprimands.

- Good, did you think about what someone could say during the Delacour ball later this week if you showed up with those bags under your eyes and that grayish complexion? Only Merlin knows that the Deshayes would love to add an illness to their list of gossips about us. - Her tone was acid when she talked about the Deshayes.

- Mother, I am sure that everything will be alright, the ball is going to be marvelous. - Louis, Marie's brother said.

- It is going to be more than good, it is going to be splendid. Gabrielle is turning ten at the end of the month and Fleur seventeen in three months, during the school year. It is time for a reunion with Aristide and Apolline about a marriage between you and Fleur. - Chevalier, Bosse family's patriarch was not a man of many words, but whenever he spoke everyone was silent to listen.

- Marriage? But father surely Fleur already has someone waiting for her hand? And our age difference? I've only turned fourteen, she would have to wait three years before the marriage and… - Her brother was not expecting that, Marie wished she could say the same but it had always been obvious to her that her father wanted a marriage between the two families.

- Nonsense. Your age difference don't matter, and I am sure that Aristide will be pleased with the union, we are after all the owners of the best apothecary in all magical France. - Chevalier seemed happy with the plan he had come up with. Aileas still looked at her children sternly as if they too should be happy with the plan.

- Father, I already told you that I will not marry a witch… - Louis tried to say again but Chevalier stopped him, his tone suddenly sharp.

- You are the heir of this family, it is your job to marry a respectable witch and have children that will carry our name. You won't come up with excuses for this. I won't have a queer heir! - Their father never raised his voice, but it still felt like he did when he said the last sentence.

- I think I heard wrong, but it seems that you are under the impression that Louis is the sole heir of this family. I am the one that holds the heir ring, not him. I am the oldest, it is to me that the magic in this home will respond when you are gone, not him, at least not until he gets married and become the head. He may be the son of this family, but that doesn't make him the only heir. - Marie knew she shouldn't have said that, it was never good to remind her father that she was the oldest of the twins.

When Aileas became pregnant, Chevalier was sure that he was getting the heir he always wanted, even when they discovered she was expecting twins he didn't care to discover the babies genders, but when they were born, a girl came first and all her father's plans for they lives were shattered. Even though he still had a heir, the magic in the family wasn't going to respond to the boy the same way it would for the girl, at least not until the girl was married to another family and the boy had his own marriage, years of planning went downhill in a second. Because to Chevalier Bosse, the firstborn in a family should be the male heir, as he would be the one considered by both norm and magic as next in line.

But Marie couldn't stay silent. Her father loved to act as if she wasn't the oldest or wouldn't be an heir for too long, after years treating her like nothing, pushing her to the shadows, taking only her brother to dinners and dances and ministerial galas he had finally come to the realization that to get really rid of her and make her brother the "perfect" heir he had to make her marry into another family as fast as he could. So for the last year and a half, he had been trying to secure a marriage contract for her, taking her to all the balls, dances and festivities he could as to present her to possible suitors. So the moment she turned 16, when she became old enough to marry but not legally an adult, so she couldn't choose to not get married, she would be out of his life.

If that wasn't enough to make her mad, there was her parents reaction to her brother coming out and their actions after that. She had always known that her brother was gay, but when he had come out to their parents before the school year began, they took it as a surprise, and since then were trying to change that "wrongness" in him, as they liked to say. Talking about courtship and marriage with girls. It didn't matter that not being straight was normal in the magical world and even in the muggle world it was starting to get accepted, it didn't matter that magical same sex couples could have children, blood related children, using a potion, spells and other things, it didn't matter that even without all of this his happiness should be more important than anything. To her parents it was shameful that their son was not straight, it was a sin and something they had to change.

- Do not talk to me like that girl. Louis is the one that will carry this family name, you are only here because I couldn't get rid of you yet. The moment you marry into another family, you will never set foot in this house again, you will be dead to us. - Marie never met anyone else that could sound so cold and heartless when talking about their own children.

- Don't talk like that Marie, your father is only thinking about what is best for this family, and a marriage between the Delacours and our family would be good. Your brother should be happy about it, the Delacours are lovely and Fleur is your friend Louis, I don't see why you shouldn't be agreeable with this union. But this is a subject for another time. We need to discuss the upcoming ball. The minister will be there, as well as other influential families, you need to be on your best behavior. You know I will be running for a position on the ministry and you father expects to get new contracts for potion ingredients as well as maybe a marriage offer for you, Marie. - Her tone was light as if she didn't just brushed off all the hurtful things her husband had just said to their daughter. Aileas drank a bit of her tea before speaking again, both her children's attention on her. - Your clothes for the event were already chosen and will be ready on the evening of that day. Do not embarrass us.

- Of course mother, we would never do that. - Louis voice was low and almost too quiet to be heard, all that Marie wanted to do at that moment was to hug him or maybe punch their father, she wasn't really sure. - If you excuse us, we should get ready for our lessons today.

- Wait, that's not all that we have to talk about. - Marie knew that her brother wanted to get as far away as possible now, but she felt that today was the day her parents would answer her questions, even if she had just angered their father. For the past seven days they danced around the subject every time she brought it up, but now, maybe they would actually tell everything. - What did you mean that next school year we are going to Hogwarts? And that the reason for that is that you fear that someone will try to kill us if we stay here? Who would do that and why? Why just now? What aren't you telling us?

- I don't think you need to know. - Chevalier said, his voice stern. - But your mother seems to think that if you know more about our reason you will understand and agree with us. Even if it doesn't matter if you agree or not, we decided to tell you more.

- As we said when you got back from Beauxbatons, next school year both of you are going to study at Hogwarts, headmaster Dumbledore has agreed to let you start your fourth year with the other students. We think it is best if you stay near Dumbledore because rumor has it that there's a group of people that are planning to bring the Dark Lord back and it would make sense that this group wishes for your father, as the owner of the best apothecary in France and someone with a lot of contacts, to help them. As we don't agree with them and your father won't help them, we fear that they will try to hurt you as a way to make us cooperate. And if you are close to Dumbledore we believe that you will be safer, as he is a powerful wizard and even the Dark Lord feared him.

- You are saying that because of a rumor you will send us to another country and school? - Louis asked, he clearly didn't believe those rumors could be true. Marie herself was skeptical, but she believed that it wasn't the only motive her parents had to send them away, to give that much freedom to them, to let their grasp on their lives to lessen.

- It's not just the rumors, we were contacted by some of those people throughout the past year and there's been some activity surrounding prisoners participants of this group. - Aileas said calmly.

- Death Eaters. You can call them by the name they adopted, mother. What you are saying is that Death Eaters, the Dark Lord's followers, contacted you, they want to recruit you and you are sending us away because of it. - Marie was certain that there was more to it then what they were told, but it was enough for now. They knew it wasn't safe for them if death eaters were after their father's help. She could discover what they were keeping a secret later. - Thank you for telling us, of course we understand why you are doing this. If you excuse us, it really is time for us to get ready for our lessons.

Marie got up while she spoke, she looked over to her brother to see that he was doing the same. The elves opened the doors for them and the room was silent during their walk to the threshold. When they got there, their father spoke again.

- You will be escorted to all places outside the house, at all times. We may be safe for now while they believe we are thinking about their request, but we won't be reckless. This is non-negotiable. - When the twins looked over to him, he was once again looking through the newspaper.

- Of course father. Have a good day. - Louis was the one to answer him, his tone once again light. He took Marie's hand in his and together both made their way to their rooms' floor.
