Warning: There are going to be mentions of abuse in this story as well as the descriptions of the aftermath of abuse. This is a femHarry fanfiction. There will be Severitus as Severus is her father. There will be slight Albus Dumbledore bashing but he is mostly good, other than using Severus and Rosalie (femHarry) for the greater good, or trying to. I am not completely sure of the ships yet, but Ron and Hermione will get together, there will be some slash, but I am not sure who with yet, possibly some mpreg as well. I may also include teenage pregnancy at some point but I am not 100% certain yet, I personally am interested in writing about someone being pregnant at Hogwarts, but we'll see where I lead this story when I get there.

Disclaimer: I don't own Harry Potter or the characters, settings, etc. except ones I create myself. I, unfortunately, am not J.K. Rowling. This will be the first story in a series portraying her years at Hogwarts and beyond. Although, I will be changing some of the deaths that occur in the series, but I am not telling you which ones, you will have to continue reading in order to find out.

Enjoy!

Severus' Daughter: Year One

Chapter one: The Truth Revealed

Severus Snape was sitting in his office at Hogwarts signing his last few pieces of paperwork before he could go home for the holidays. It was the beginning of the first week of summer and he was glad he could get some time away from the students who enjoyed making his life harder every day.

There was a knock on his door, but he didn't stop signing as he called out for the person to enter. He heard the door open and close, and someone walking towards his desk but still didn't look up from his paperwork.

"Severus, are you almost done with your paperwork?" Minerva asked her adopted son.

"Yes, I just have to sign this last one and then we can go. I sent Bitsy with all of my belongings already." Severus replied as he signed the last piece of parchment and tapped his wand against the pile of filled out paperwork, sending them to the Headmasters' Office. "Is Albus joining us at any point this summer?" He asked as he finally looked up at his mother.

"I don't know. We'll have to wait and see."

Severus nodded and stood from his seat, going over to the door of his office and casting his usual locking charms before heading over to the fireplace where his mother was waiting for him. She went through the floo to their home first. He dimmed the light in the room, stepped into the fireplace, dropped the handful of floo powder and called out his destination, "Moon Cottage," and then he was gone.

…

That night Severus entered his bedroom to get ready for bed to find an envelope on his bed. He walked over and picked the envelope up, it had his name on it, in very familiar handwriting.

Lily.

He was confused. Lily was dead. There was no way she could be writing to him.

He sat on his bed and turned the envelope over, unfolding it and pulling out the letter within. He unfolded the parchment and leant against the ebony headboard to read it.

My Dearest Severus,

I know you're probably wondering why I am writing to you, and how I am writing to you. I put this letter on a time delay, to be delivered at the beginning of the summer holidays in the year 1991 based on some conditions.

The first condition being that I am dead, in which case I am sorry that I am not there, but know that I love you, always. The second being that the memory charm placed on you and several others by Albus hasn't been lifted as he promised he would have done had I died.

This probably confuses you, but yes, just under ten years ago now Albus placed a memory charm on you and some of our friends/family so that you would forget certain things so you, myself and our child would be safe throughout the rest of the war. He promised that he would undo it and return your real memories in the case the I died or the war came to an end, but he obviously hasn't otherwise you wouldn't be reading this letter. And you may notice that I said 'our child', currently you may believe that my child is James', that is what you were made to believe in these false memories, but that is not true. My daughter, Rosalie Eileen Lily Evans, is also your daughter. You used to call her Rosie.

I know you probably don't believe me at this point, which is why I created a charm which would give you your true memories back, as well as return the memories of others who had had their memories changed. The charm is memorias revelare tuo verum est and you will need to repeat this five times for it to work.

When your true memories have returned I need you to find our daughter and look after her. I have reason to believe that Albus may leave her with my sister if I die, in which case she will be at number 4 Privet Drive, Little Whinging, Surrey. Find her, raise her, love her, cherish her. You were such a wonderful father to her in that year that we were together, I know you will be a wonderful father to her from now on.

But also keep an eye on Albus, I don't think he is as trustworthy as he portrays himself to be. Especially since you are reading this letter because he failed to complete his promise.

Most of the things I own are in a vault at Gringotts waiting for you, as well as some of Rosalie's things. Just speak to Griphook and he will take you there. Also, James has made Rosalie his heir, so you will have to speak to Griphook about that as well.

Just remember that I love you Severus, and I always will.

Lily.

Severus was still slightly confused when he came to the end of the letter, but he said the charm five times anyway, curious as to whether what was written was true, Lily had never lied to him before, why would she lie to him about something like this?

As soon as he had finished the fifth chant he doubled over as his head was filled with memories he hadn't had for nearly ten years. Memories of Lily forgiving him in their fifth year. Of them dating since sixth year. Of the Marauders apologising and them becoming friends. Of the day he proposed to Lily. Of their wedding day. Of the day she told him she was pregnant. Of the times where their daughter kicked in Lily's belly. Of the day Rosie was born. Of her first year of life. Of her first birthday. Of the day he lost everything.

He was panting on his bed, trying to sort through the memories, when his mother knocked on the door and entered.

"Severus, what just happened?" She asked, sitting on the bed, clutching her head as she also tried to sort through the onslaught of new memories.

He just handed her the letter, which she read.

"We need to go and get her. God knows how she is being treated with Petunia and her whale of a husband." Severus said once he had sorted through his memories. Minerva nodded in response.

"Let's go now." She said.

They stood and left the house, walking to the edge of the wards in silence, and as soon as they were outside the wards they apparated to the house Rosalie was in.

…

Severus knocked on the door of number 4 Privet Drive and it wasn't long before they heard a grumbling man come down the stairs and open the door. They were face to face with Vernon Dursley who had just realised that there were two… wizards on the other side of his door.

"What the hell do you freaks think you are doing? Knocking on my door at this time of night. I was just about to go to bed." Vernon growled.

"It's good to see you too, Mr Dursley." Severus started sarcastically. "However, we are just here to collect my daughter, and then we will be on our way, you won't ever have to see us again."

"And who is your daughter? There aren't any little girls in this house."

"Don't lie. My daughter happens to be your niece, unfortunately for her, and I know that she is living here. So tell me where she is or I will force myself in and hex you a few times before finding her myself." Severus threatened, pointing his wand at the trembling man.

"She's at a friends' house for the night." Vernon whimpered, staring at the wand, scared.

Severus pushed himself into the home, his mother followed behind him. "Point me Rosalie Evans." His wand moved in the palm of his hand to point at the cupboard under the stairs. The door of which had a large lock on.

He turned and growled at Vernon who was glaring at them. "Why does my wand tell me that my daughter is in the cupboard under the stairs?" He spat.

"Obviously your wand is stupid. I told you, she is at her friends' house."

"We'll see."

Severus turned back to the cupboard, wandlessly and wordlessly unlocked the door, and opened it.

What he found, after casting a silent lumos so he was able to see into the dark cupboard, broke his heart.

His daughter, his tiny daughter, was curled up on the floor wearing rags that were more than twice the size of her. She was bloodied and bruised. Her body was skeletal. There were burn marks on her arms. She appeared to be sleeping. There were tear tracks on her cheeks. Her long black hair was greasy and tangled, it also had traces of blood in it. He knelt next to her small frame and, as gently as he could, lifted her out of the cupboard and into his arms. She whimpered but stayed asleep. He saw the blood scattered on the walls of the cupboard, and the floor. He saw the bucket of what could only be urine and other bodily products in the corner. He saw the small piece of paper with the words 'Rosalie's Room' on it. He saw the small stuffed wolf hiding under the shelf and summoned it, recognising it as the toy that Remus gave her as a baby. He gave it to his daughter who clung to it right away, still asleep as she did so.

Slowly, so as not to jostle his daughters' injured body too much, he stood with her in his arms. As soon as his mother, who had been standing with her wand pointed at Vernon Dursley, saw her adopted granddaughter she gasped and growled at the whale of a man who had dared to hurt her precious grandchild.

Severus glared at him as well. He kicked the door to the cupboard shut and wandlessly and wordlessly spelled it to remain shut to everyone who wasn't an Auror, Severus, or his mother.

"Now, I am going to take my daughter home, where I am going to heal her and look after her the way she should have been looked after her all these years. I have spelled the door to the cupboard so that it can only be opened by an Auror, myself, or my mother, and I am going to return to make sure you are punished for what you have done to my baby. I am going to do a complete diagnostic exam on her to show us everything that you have ever done to harm her physically, and we can quite easily find out what you have done to her mentally and emotionally as well, although, judging by your very unpleasant welcome we can guess that you called her a 'freak' among other things. With any hope you will be going to Azkaban, along with your wife depending on what she did to my daughter. And your son, well, depending on what he did to her also, may also be punished in some way. I have also put a ward around the house so that you can't leave for extended periods of time. By that I mean anything longer than twenty four hours. I am not letting you or your family escape being punished for hurting my child. Mum, let's go." He led Minerva out of the house and to the apparation point where they apparated home and sped to the house in a hurry.

…

Severus placed his injured daughter gently on his bed and instantly started casting the diagnostic spell.

"Mum, I need you to go to my potions lab and grab me my healing bag. I then need you to get me a bowl of warm water, some flannels, and one of your looser night gowns which you can shrink so it will fit her." He said as the parchment and quill writing all of his daughters' ailments kept growing.

Minerva nodded and left the room in a hurry.

Severus magically removed his daughters' outer layer of clothing, keeping her underwear on, and what he saw nearly made the tears that were gathering in his eyes spill over the edge. She was so skinny you could count her ribs, her arms and legs were basically twigs. She was covered in bruises, burns and welts, some of which were bleeding, but most of which were scars.

When Minerva arrived with his bag and the bowl of water he asked for he started cleaning the blood off his daughter, Minerva gently lifting her into a sitting position so he could clean her back which was even more covered in scars, welts and bruises. He magically cleaned her long black hair and had Minerva tie it into a high bun so it wouldn't get in the way.

He rubbed bruise balm on her bruises, magically sealed her open wounds before rubbing scar balm into her scars, it wouldn't get rid of all of them but it would get rid of some. He rubbed burn balm into her burns. And then he looked at the diagnostic results, which had finally stopped growing.

He tried to contain his fury over what had happened to his daughter over the past ten years. She had received hundreds of bruises since she was placed with the Dursleys, starting the night she was placed with them. They started whipping her at three and had received a lot of welts since then. They had started burning various parts of her body at four. They had given her five concussions over the years, the first being when she was five. They had started drowning her at five also, leading to damaged lungs which is the cause of her deep, ragged breathing. They have broken a number of bones in her body since she was five as well, some of which hadn't healed correctly and would need to be reset. She was severely malnourished, the height of an eight year old. She would need a nutrient potion three times a day, one with each meal, and snacks to go between the meals. They had also never sought out treatment for her when she was sick. It seems that she is only alive because her magic is keeping her alive and healing her as much as it could.

He put a light sleeping spell on her so she wouldn't wake up during the rebreaking and mending of the bones that weren't properly aligned. When that was done he spelled a nutrient potion into her stomach, along with a pain reliever potion. He also spelled into her stomach a potion that would mend her lungs and make breathing easier for her.

He magically dressed her in the night gown that Minerva brought with her, and that was all he could do for her until she woke up and he knew how she was feeling. He knew there was some damage to her spine as well, but he couldn't do anything about it until she was awake and he knew how she felt. He conjured an armchair next to the bed and sat in it, not noticing Minerva do the same on the other side of his bed as he stared at his sleeping daughter, taking in her looks. Her skin was pale, something she inherited from both parents, she had his high cheek bones, his hair colour, although Lily's waves, thankfully she had Lily's small straight nose. He knew that as a baby she grew into having Lily's eyes as well, he wondered if they were still that bright shade of green. She had his long fingers, that were still clutching the stuffed wolf. She was perfect. The perfect mixture of himself and Lily.

They heard the floo go off downstairs.

"Severus! Minerva! Are you home?" The familiar voice of Remus Lupin called up the stairs.

Minerva left to bring their guest upstairs and he, gently, held onto his daughters cool, pale hand. Soon Minerva and Remus entered the room and Remus stared at his sleeping goddaughter on the bed, sinking into the armchair Minerva conjured for him next to Severus' as he saw the scars, burns and bruises that littered her delicate body.

"What happened to her?" Remus whispered.

"She was left with Petunia and her whale of a husband."

That was all Severus needed to say for Remus to realise what happened to his beloved goddaughter.

"Where are they?" He growled.

"That doesn't matter right now. They'll get what's coming to them eventually. I've put a ward on their house to stop them from leaving, and put a ward on the place they kept her to stop them from tampering with it. Right now we just have to make sure Rosie is okay." Severus replied.

"Who left her with them?" Remus breathed, trying to get ahold of his anger.

"Do you even have to ask? It was the man who conveniently forgot to return our memories to us. You know, the man I call father." Severus sneered. "And as much as I would like to go and give him a piece of my mind, right now I am going to stay with my daughter and make sure she is okay."

Remus just nodded and went back to watching his goddaughter sleep, thankful that he had had his memories returned and that his goddaughter and best friend were back in his life.

Hello everyone, hope you are all well! So, I am currently suffering from the flu and when I have the flu I tend to sit around reading either books or fanfiction all day, and I found this amazing fanfiction in which Harry is a girl, and Severus is her father, and I wanted to do something like that because I loved it so much and I wanted to do my own version of that AU. The fanfiction is called Severus' Rose and there is one for each year at Hogwarts, it is by WrittenWord1 if you want to go and check it out.

Anyhow, hope you enjoyed it. And I know I haven't updated at least one of my fanfictions in a long time, but I have been really ill lately, and my conditions have gotten worse, and I have had family and work issues so I haven't really had much time. But I will be updating soon since I am getting slightly better health wise.

I will update again soon.

Please review!
