Summary of book 1:
TW: Mentions of death, kidnapping and rape

A new prophecy has popped up in the Wizarding World. The Dark Lord and Harry Potter need help from the Keeper of the Diamond to destroy each other. It’s later revealed that the Keeper is Y/N, who’s from another dimension, as well as the fact that they need two diamonds - an orange and a pink one. Y/N and her friends, Laura and Vera, help Harry Potter and the rest of the Order fight Voldemort and his Death Eaters.

During their adventure, Y/N meets the Harry Potter characters. She even has lots of moments with her favourite ones, Severus Snape and Lucius Malfoy, which are even flirtatious sometimes since they are her favourite characters. She also goes to Hogwarts pretending to be a transfer student in Gryffindor where she has Potions, Defence Against the Dark Arts and Transfiguration lessons. She even gets kidnapped to Malfoy Manor where there are unfortunate events for her - such as Dolohov, who also killed her mother, almost raping her.

However, Y/N and Harry end up destroying the Dark Lord together with both the pink and the orange diamond. Their victory is celebrated with a party at Hogwarts. The three friends then bid goodbye to the Harry Potter characters before going back to their own dimension. It’s not the last time they will see one another, though.

Summary of book 2:
TW: Mentions of death, kidnapping, rape and torture

Y/N’s friends, Laura and Vera, are almost kidnapped by the Trix from the Winx Club dimension because they want the pink diamond. The two girls however escape to the Alfea school where they see someone in the Winx’s dorm they don’t expect to be working with them - which is Valtor. Y/N is assigned by Dumbledore to help the Winx Club defeat the Trix and Lord Darkar who has returned. She however gets kidnapped as well by the Trix at a party on Domino. It turns out that somebody has told Darkar that he needs both the pink and the orange diamond as well as their Keeper - that somebody is Bellatrix Lestrange who has escaped from Azkaban with Dolohov.

In Shadow Haunt, Y/N is almost raped by Dolohov and is tortured by Bellatrix and Icy. She gets saved by the Winx, the Specialists, her friends, Lupin, Black, the Trio and Snape as well as Valtor who she has flirtatious moments with since he’s her favourite Winx Club character. Snape heals her injuries as she’s left with a scar on her left thigh and on her right cheek. Lord Darkar is destroyed, Dolohov is killed by Valtor and Snape, Bellatrix is sent back to Azkaban and the Trix are sent to Light Rock Lake.

They all bid goodbye to the Winx Club characters. Tecna the Fairy of Technology upgrades the three girls’ phones so they can always contact them. At Hogwarts, Y/N’s birthday party is celebrated. They are having a good time and she gets lots of presents - one being an enchanted notebook from Snape so they can write to each other every day. A few days after the party, there is suddenly a knock on Snape’s door in his private home in Spinner’s End.

Summary of book 3:
TW: Mentions of death, kidnapping and rape

The Malfoys knock on Severus Snape’s door to hide in his home in Spinner’s End as they don’t want to go to Azkaban. While Y/N is visiting, the Malfoys are hiding in the guest room. Dumbledore somehow knows that they are there - he doesn’t turn them in, though. They are pardoned at the Ministry of Magic and can return to Malfoy Manor.

Y/N and her friends, Laura and Vera, are sent to the The Walking Dead dimension to save the Trio, Snape, Lupin and Black who have all been kidnapped by the Saviors as they were sent to help Alexandria in their war against Negan. Vera and Laura get kidnapped together with Daryl from Alexandria as well. Meanwhile, Y/N and Lucius, who has joined them on the mission, try to save them. They quickly get caught, however. At the Sanctuary, Y/N is almost raped by David the Savior - Negan saves her in time as he kills David.

They end up winning the war and capturing Negan. They let him live and put him in the cell in Alexandria. When they return back to Hogwarts, they celebrate their victory with a Halloween party. Snape and Y/N visit the Malfoys at the Manor. Their holiday is however interrupted as Dumbledore has another mission for them.

Chapter 1

Notes:

TW: Flirtatious & seductive behaviour and mentions of nakedness

Chapter Text

A week after the Halloween party at Hogwarts, Y/N is still at Malfoy Manor. She was only supposed to stay for a few days, but she has simply had too much fun here.

As they are finishing their evening tea, Narcissa rises from her chair. “I am sorry to leave on such short notice, but a friend of mine needs some advice for her date tomorrow. Poor thing has no idea what to wear or how her hair should look. I will most likely stay the night, but I will arrive tomorrow morning” she states as she giggles at her friend in distress.

Nodding, Y/N, Snape and Lucius bid Narcissa goodbye as she leaves the Manor.

Y/N can’t help but chuckle. Stella from Winx Club would LOVE to help Narcissa’s friend. She probably doesn’t know much about witch fashion, though.

She makes a mental note to send Stella a message. They were supposed to visit them, however their mission in the The Walking Dead dimension took a bit longer than expected. And then there was the Halloween party, and then she was staying at Malfoy Manor.

She wonders if they will see each other soon, or if the lemon-obsessed Headmaster of Hogwarts has other ideas.

Lucius gains Y/N and Snape’s attention. “Well, now that both Cissy and Draco are out of the Manor, why don’t we all sleep in the same room tonight? You know, like we did in that zombie dimension. Only the bed is much bigger here” he says as he smirks. Snape smirks as well while Y/N blushes.

They all then rise from their seats and go towards Lucius and Narcissa’s room. Y/N walks into her shared guest room with Snape to retrieve her weekend bag.

She then enters the room next door to see Lucius and Snape getting ready for bed as she puts down her bag. They have just brushed their teeth and are now taking off their shoes, shirts and pants. Y/N blushes at that and quickly looks away.

“Um, is it okay I take a shower first?” she shyly asks. She absolutely loves Lucius’ hair care products. She may or may not be obsessed over how soft it makes her hair feel.

Lucius smiles. “Of course you may, darling. Go ahead” he says as he gestures to the bathroom.

Nodding, Y/N enters as she starts to brush her teeth. After that, she strips out of her clothes and takes a shower. She massages the shampoo into her scalp as she relaxes. When she’s all done, she turns off the water and dries her hair and body with a green towel.

When she realises that she forgot to bring some clean clothes to the bathroom, she sighs loudly. At this point she’s more forgetful than Neville Longbottom!

She thinks of what to do now. She obviously doesn’t want to wear dirty clothes, so that leaves only one option - put on the towel, enter the bedroom to grab some clean clothes and go back here to change.

She wraps the towel around her body as she reenters the bedroom.

Snape and Lucius look at her, surprised. Snape however smirks after a while. “Did you forget to bring some clean clothes to the bathroom - again?” he asks her teasingly. Y/N’s cheeks turn a bright red colour, but she nods nonetheless.

Lucius chuckles at that. “Well, I guess you will have to sleep naked, then” he says, smirking at her.

Y/N widens her eyes. Is Lucius serious?

Both men laugh at her reaction. “Relax, Y/N. That was a joke. Unless you do wish to sleep naked, of course” Lucius says as he wiggles his eyebrows in a seductive manner. Y/N’s cheeks are now crimson red.

Snape coughs a few times. “I can just use my magic to dress you. Just put what you want to wear on the bed and I will do the rest” he offers.

Nodding, Y/N grabs some clean underwear and her Snape t-shirt from her bag. She shyly puts them on the bed - the t-shirt on top of the underwear so they don’t see it.

Both Lucius and Snape smirk. “No need to hide your underwear, princess. We will see them anyway as the t-shirt does not cover your bottom” Snape says.

With a flick of his wand, Y/N is dressed as the towel has replaced the clothing on the bed. Y/N gives a shy smile while still blushing. “Thank you, Sev” she says.

Lucius then pats the spot between him and Snape. “Come and lie down, Y/N” he says as he waits for her to lie down between them.

Nodding, she does so as she crawls on the bed to the assigned spot. Snape then gently covers her with the duvet. She smiles at him.

She then wraps her right arm around Lucius’ left and her left arm around Snape’s right. She gives each their hand a gentle kiss.

“Good night, Luci and Sev” she mutters as she yawns. She then closes her eyes and smiles as she quickly falls asleep, hugging their arms.

They both smirk at her sleeping figure. “Good night, princess” Snape whispers in her ear while Lucius gently strokes her right, scarred cheek with his thumb. After a while, Snape and Lucius fall asleep as well.

Meanwhile in their dimension, Vera and Laura are playing Mario Party 8 with the Trio. Since Y/N has been at Malfoy Manor for a whole week, they decided to invite the three Gryffindors over to play some games.

Vera sighs. “I wonder if she’s going to move in with them?” she questions.

Ron snorts at that. “How could anyone live with the Malfoys? And Professor Snape? Bloody hell, imagine sharing a kitchen and bathroom with the grumpy Potions Master” he says as he grimaces at the thought.

He can only imagine how grumpy the Head of Slytherin must be in the early mornings before any coffee. Definitely more than he is already.

Hermione rolls her eyes. “I am sure they are not that bad. And you would be grumpy too if you had to teach a bunch of students who do not pay attention in class” she states.

Harry laughs at that. “Well, Y/N seems to like them, so she should be safe” he says.

Ron grimaces once again. “I still don’t understand how she likes Snape. And how can she like the Malfoys!” he exclaims.

Laura gives a small smirk. “Well, she more than LIKES them, so yeah, she’s definitely safe” she says as Vera rolls the dice in the game.

Both boys widen their eyes. They do not want to know in what way Laura is referring to.

It’s suddenly time for a four-player minigame. “Woohoo, minigame time! I love those!” Ron exclaims, sounding excited.

Vera then turns to Laura. “Well, I played in the last minigame, so it’s your turn now” she states.

As only four people can play at a time, Laura and Vera have agreed to share the remote. They then switch turns each time. Nodding, Laura grabs the Wii remote.

The Trio gulps. Laura ALWAYS wins, it’s kind of annoying. Well, they will have to fight for second place, then.

The minigame they are playing is called “Twisted and Sick” which is where the players have to get on the other side as they are jumping from platform to platform as they are rotating.

As they are playing, no one is in doubt - Laura will win for sure. When it ends, everyone is surprised to see Harry come in first place.

Laura blinks a few times. What just happened? She then takes her pillow and buries her face in it as she’s screaming into the pillow.

Harry looks at her, a bit nervous.

“Um, is she okay?” Ron hesitantly asks after a while.

Vera looks between Laura and the three Gryffindors. “Nope, she’s not” she simply says.

Suddenly, somebody emerges in the room. It’s McGonagall. “Hello, it is good to see you all are awake. I hope I am not interrupting- Are you okay, dear?” she asks Laura while looking worried. Laura gives a thumbs up while her face is still buried in her pillow.

Hermione chuckles. “She is fine, professor. She just lost in a game. Harry won” she says as she gives her friend a proud smile. Harry smiles back.

McGonagall chuckles, too. “Well, that is good to know. Anyway, I know it is a bit late, but the Headmaster would like to see you” she states.

Laura sighs while her face is still buried in her pillow. Can’t Dumbledore give them a break? She then removes the pillow from her face. “What about Y/N? She’s still with the Malfoys” Laura states.

McGonagall looks a bit surprised. Y/N is still with the Malfoys and Severus? It’s been a week! She wondered why the girl wasn’t here in the room anyway.

She clears her throat. “Very well, I know for a fact that Lucius Malfoy does not want to be interrupted this late. I will have to let them know in the morning. If you five come with me, then you can stay at Hogwarts in the Gryffindor dorms until Y/N arrives tomorrow as well” she suggests.

Nodding, all the teenagers stand up. McGonagall then apparates them all to Hogsmeade.
