A/N: Hello! Thank you for clicking this story. This is a Tomione, and it will have mature content (don't want to give anything away but I'm sure you can guess what I mean by that) if there's anything that I think will be triggering I'll put a warning up, but I doubt there will be anything like that. This story isn't going to be very dark, or at least as non-dark as it can be when you have Tom Riddle as one of the leading characters. Anyway, I'm rambling. I hope you like the prologue, please leave me a review to tell me what you think.

Hermione woke up with a feeling of dread settling in the pit of her stomach. It was her first day in Seventh Year, and she was Head Girl, so she ought to be excited. But she wasn't. She had a dreadful sense of foreboding that she couldn't seem to shift.

Pull yourself together, Hermione. She thought as she stared at herself in the mirror. Her curls were a wild and untamed mess and she could not be bothered to deal with it today so she just put it in a messy bun and ignored the dark circles under her eyes.

Hermione walked to breakfast with Harry and Ron on her heels, they were both wondering what was wrong with her as she was unusually quiet.

Ron untactfully said "'Mione? are you on your...you know. You're acting very strangely."

Hermione bit down her anger. The last thing she wanted was to get into another one of the characteristic arguments she usually shared with him. "I'm fine, Ronald." she said, her anger seeping through in her tone.

"Merlin, calm down! I was just asking!" He harrumphed and tried to look at Harry for backup, but he ignored Ron and stared at Hermione worriedly. It was usually him who was quiet and subdued nowadays, what with Voldemort at large, not Hermione.

They walked to the Gryffindor table and Hermione poured herself some pumpkin juice and spread some marmalade onto her toast, even though she didn't feel hungry, she was still uncharacteristically unnerved.

There was chatter going on around her but she tried to tone it out. She felt eyes on her, and looked around the great hall to see who'd been staring at her and her gaze fell on Dumbledore, who was staring at her intently. Hermione started and looked around her thinking she'd misjudged it and he was looking at someone else, Hermione realized that Harry was sitting next to her and Dumbledore must have been looking at him instead. There was no reason for him to stare at her like that, as if deeply assessing, but Harry on the otherhand was close with Dumbledore and they'd been having meetings in his office regularly, so he probably wanted to communicate something with him. Hermione soon forgot about it and went back to eating her toast.

The owls soon swooped overhead and Hermione was surprised when a unfamiliar white owl delivered her a letter. Hermione gave the owl a bit of crust after she pulled the letter from it's beak.

The parchment was thick and expensive looking, and Hermione didn't recognize the penmanship.

"Who's that from?" Ron managed to choke out while stuffing his face with sausages.

"I don't know, I haven't opened it yet." Hermione said with a sigh. Sometimes talking to Ron was like talking to a five year old.

She turned the envelope around and noticed the seal was unfamiliar too. It had a crow on it. Or it was some kind of bird, Hermione wasn't sure. She ripped the seal and opened the letter.

Before Hermione had time to process anything the letter had said, it suddenly burst into flames. She heard multiple gasps around her, but she wasn't focused on them, instead she was staring in horror at her hands which were emitting a bright light, it spread quickly down her arms and to the rest of her body. Soon she was glowing, and the whole of the school was staring at her. The last thing she heard before she vanished with a pop was harry shouting "Hermione!"
