Hermione sat alone once again in the window seat of her house, her daughter Cassie sleeping peacefully upstairs. She sighed as she thought of all that had happened since she started at Hogwarts.

Her mind drifted first towards the joy and confusion she'd felt at receiving her Hogwarts letter and to her first year, when she, Harry and Ron had saved the Philosophers stone from Voldemort's clutches; then to her second year when she was petrified due to the Chamber of Secrets being reopened. There would always be memories of her third year, when Harry met his Godfather and learnt the truth about what had happened to his parents, how their friend Peter Pettigrew and not Sirius Black betrayed the pair, how she travelled through time to save Sirius and Buckbeak the Hippogriff for whom she had hit Draco Malfoy because of.

However her fourth year, the year the Triwizard contest was held at Hogwarts was by far the most memorable. It brought her first boyfriend, of sorts, and the news of the death of a friend with the rebirth of an enemy. Voldemort was back, and he was human. Also when she returned to her parents she discovered her new baby sister, Isabel, and the news of her parents divorce, her father nowhere to be seen, she later learnt he was in America. Somehow she convinced her mother to change her and Isabel's last names to her mother's maiden name, claiming it was independence from her father but just not wanting her family at threat from the new Voldemort.

Her fifth year, the year Sirius died. She furiously tried to block those memories from her mind but they spilt in anyways. Before her sixth and seventh years, the years in which Dumbledore died and McGonagall fought for control of the school, the year that she started to date Ron and the year in which herself and the other two thirds of the golden trio prepared to fight Voldemort.

Hermione's mind soon was onto the year after graduating from Hogwarts. So many brave friends died during the final battle before Harry finally overcame Voldemort. How Hermione ran away after the battle, had to run from the images of Hagrid, Charlie Weasley, Andromeda Tonks and so many other friends gruesomely positioned, lying dead on the floor. She had run to her father, to America, for a new start. She had planned on getting away from it all, away from the magic but things were not going to happen that way. When Hermione had been in America for 1 month, aged 18 she was raped. Because of that incident her parents spoke to each other again, as Hermione's mother and Izzy had flown over from England to check she was okay.

Though Hermione was soon physically fine, she discovered she was pregnant, and that helped her to look back on the rape in a different light, although it was still bad to remember, she got her daughter Cassandra Faith Granger from it and now couldn't imagine a life without her.

Hermione was shaken out of her thoughts to the sound of Cassie, now age 6, jumping down the stairs. "Mummy come, look, there's an owl in my bedroom, come on Mummy, come!"

She found herself standing slowly as she made her way to her daughter's room, now at 25 years of age she was not too keen on the idea of a message from the wizarding world after 7 years.

Upon entering the room, she soon spotted the cute fuzzy brown owl that sat on the top of Cassie's cupboard. The owl flew swiftly over, sticking out its right leg before flying off once the letter had been received.

Hands trembling ever so slightly Hermione opened the envelope, skim reading through it quickly, though she soon realised that the wizarding world had not caught her, just that they were going to. Soon. One way or the other.

Hey Hermione,

Guess what! I got a Hogwarts letter, Mum said it was up to me whether I went or not so I said yes, I know that you left that world but surely no one will remember one little Muggleborn huh? No one important anyway, no offence. So anyway, I went to Diagon Alley where I got my owl, Maisie, isn't she cute? Mum said I had to tell you that the Headmistress of Hogwarts, McGonagall I think it is, well she's coming to visit, apparently she visits all Muggleborn witches and wizards before they start at Hogwarts, to check they have no problems, Mum thinks that she might be recognised by this, lady, or whoever she is, I don't know why as she hasn't seen Mum for years and years, a whole 14years, why would she be recognised, so, Mya, the lady is coming on Tuesday and Mum said to tell you in case you wanted to come. Give my love to my favourite (and only) niece will you. Love you both loads, your little sister Izzy. XxXx

p.s. Mum said to add that the flue thingy is up, don't know what she's on about though.

Hermione let out a small giggle at her sister's attempt to spell 'Floo', Hermione would have to give her a lesson on wizarding ways before she left for Hogwarts. Hermione's sister, the same Hermione Granger named 'Smartest Witch in 5 Centuries' by the Daily Prophet and Witch Weekly, was not about to be allowed to taint her older sister's name in any way.

As Hermione turned around making her way downstairs she found Cassie sitting quietly playing with the doll she was given for her fourth birthday by her Auntie Izzy. Hermione smiled at her briefly before continuing her way towards the kitchen where she could think about what she was going to do.

While she sat and she pondered, all the memories came back, she knew that she wanted Cassie to be raised as a witch but could she face returning to Harry and Ron after leaving them, most likely when they needed her the most? In her heart though she knew that she was being given a valid reason to return, and should take advantage of the situation.

Hermione walked over to the fireplace, opening up the small pot of powder that she had always kept in case of an emergency. Hey, this will scare the living daylights out of my sister. She grinned as she hoped her unsuspecting sister would be waiting by the fireplace.

As her head stuck through the fire and she clearly stated the address of her mother's house she felt the familiar tingle of the Floo travel around her neck. She smiled. She hadn't even spoken to anyone yet, though she knew that she was where she was supposed to be, surrounded by magic.

The smoke cleared and Hermione looked around to see the familiar sight of her house in England, and her mother's feet, glancing up she spotted her mother smiling at her. "I knew that we would see you soon Mione, knew you would be flooing in soon.

Hermione wrinkled her nose playfully. "Hmm, well today's Monday and McGonagall will be here tomorrow so I figured that we needed to talk, now."

Hermione's mother, Laura, continued to smile at Hermione before saying, "Okay sweetie, but how is Cassie?"

Hermione raised an eyebrow sceptically, "Cass is fine, why wouldn't she be?"

"Oh I don't doubt that you aren't looking after her properly, just asking how she is", Laura replied, before adding sarcastically, "do I have permission to ask how you are?"

"Sorry Mum, it's just, I have a lot going through my head right now, I didn't mean to snap."

"I know you didn't sweetie" Laura answered as she made her way over to sit down on the couch, "so, do you think McGonagall will recognise me?"

Hermione sighed as she replied, "I'm pretty sure she will, she may have only met you two or three times but I'm sure she will remember."

Laura stared Hermione in the eyes as she asked, "why would she recognise me, like Izzy said, you might have been one of the smartest witches 7years ago but it's not like you saved the world or anything."

"…"

Laura's eyes widened as she looked at her eldest daughter, "you saved the world? Why? When? How come you didn't tell me?"

Hermione cut her mother off, "There was a war going on, I only helped, with Harry and Ron. It was because one wizard thought he could take over the Wizarding World, and very nearly succeeded but we stopped him. It was 7years ago and the reason I left that World and I never told you as I didn't want you to worry."

"…" Now Laura was speechless, she couldn't imagine her daughter fighting in a war, she couldn't imagine how she hadn't noticed, Hermione's voice started to bring her back to reality.

"Mum, look, we won the war, the Wizarding World is safe, I left that World as I couldn't face seeing all the people who got badly injured and cursed, or all the families of those who died…but I don't want Cassie to miss out on life as a witch because of me. I was planning on going to rejoin the Wizarding World soon anyways, well, sometime in the next 5 years, but Mum, this is the perfect opportunity to get back there. Listen, just, Cassie and I will be arriving later tonight, say 7pm your time by Floo. If you feel like it leave Izzy in front of the fire with no warning, but please, don't tell her about what I just told you, she'll find it out anyway no doubt… See you later?"

Laura gave in as she looked at Hermione's pleading eyes and just nodded her head in defeat.

Living in my own world
Didn't understand
That anything can happen
When you take a chance
